You've decided to start IVF — or you're trying to understand what you're about to go through. Either way, the best thing you can do right now is understand the actual process, step by step, day by day.

Most clinic websites give you a vague flowchart. This guide gives you the real timeline: what happens on which day, what you'll feel, what to ask your doctor, and what the numbers mean. India-specific context throughout.

The Two Main IVF Protocols Used in India

Before the day-by-day breakdown, you need to know which protocol you're on — because the timeline differs.

Protocol: Antagonist protocol (short protocol) · How it works: GnRH antagonist (Cetrotide/Ganirelix) added mid-stimulation to prevent premature ovulation · Timeline: ~14–16 days total · Ideal for: Most patients; standard first-line in most Indian clinics today

Protocol: Long agonist protocol (long protocol) · How it works: GnRH agonist (Lupron/Buserelin) starts in the cycle *before* IVF to suppress ovaries first · Timeline: ~4–6 weeks total · Ideal for: Certain complex cases; higher-volume clinics may still use it routinely

Ask your doctor: "Which protocol are you planning for me, and why?"

For this guide, we'll walk through the antagonist protocol as the primary timeline (it's what most Indian patients go through today), with notes on where long protocol differs.

Before IVF Starts: The Workup Phase (1–3 months before cycle)

IVF doesn't start on Day 1 of stimulation. It starts with a workup that determines whether you're ready to proceed and what your protocol should look like.

What happens during the workup

For the woman:

  • AMH (Anti-Müllerian Hormone): Measures ovarian reserve. Done on any day. Normal range for IVF candidates: 1–3.5 ng/mL. Low AMH (<0.5 ng/mL) doesn't rule out IVF but affects medication dosing.
  • Antral Follicle Count (AFC): Ultrasound on Day 2–3 of your period. Counts the small follicles visible in both ovaries. 10–20 follicles is considered good reserve.
  • Day 2–3 hormone panel: FSH, LH, Estradiol (E2). High FSH (>10–12 IU/L) can indicate diminished reserve.
  • Thyroid panel: TSH must be controlled before IVF. Most clinics want TSH below 2.5 mIU/L.
  • Uterine assessment: Sonohysterography or hysteroscopy to check the uterine cavity for fibroids, polyps, or adhesions that could affect embryo implantation.
  • Infectious disease screening: HIV, Hepatitis B/C, VDRL.

For the man:

  • Semen analysis: Sperm count, motility, morphology. Done after 2–5 days of abstinence.
  • DNA fragmentation test (DFI): Not routine everywhere, but important if there's been unexplained failure or high abstinence periods.
  • Infectious disease screening: Same panel as above.

Questions to ask at your workup appointment

- What does my AMH/AFC suggest about my response to stimulation? - What FSH dose are you planning to use? - Do I need a hysteroscopy before starting? - Is there anything I should change (weight, supplements, smoking, thyroid levels) before we begin? - What is my estimated number of eggs and embryos based on my tests?

The IVF Cycle Timeline: Day by Day

Day 1 — Your Period Starts. The Clock Begins.

Day 1 of your IVF cycle is Day 1 of your period (the first day of full flow, not spotting). Call your clinic that morning. They will schedule your baseline scan for Day 2 or Day 3.

What you're feeling: Normal period cramping. For many couples, this day carries enormous emotional weight — it's the official start.

Day 2–3 — Baseline Scan and Starting Injections

What happens:

  • Transvaginal ultrasound to confirm your ovaries are quiet (no large cysts, low baseline estradiol).
  • If cleared, you start FSH injections (gonadotropins) that evening.

Medications started:

  • Gonadotropins (FSH ± LH): Injections to stimulate follicle growth. Common brands in India: Gonal-F, Puregon, Fostimon, Meriofert, Recagon. Typical dose: 150–300 IU/day depending on your reserve and age. Poor responders may require up to 450 IU/day — always per physician protocol.
  • Your clinic nurse will train you (or your partner) to inject. These are subcutaneous injections — the needle is small, the area is your lower abdomen.

What you're feeling: Mild nervousness about self-injection. This passes within 2 days.

Indian context: Medications are typically purchased from the hospital pharmacy or an authorised fertility pharmacy. Keep them refrigerated (2–8°C). Do not freeze.

Days 4–5 — Stimulation Continues

Continue daily injections at the same time each day (±30 minutes). No monitoring scan yet unless your clinic uses a Day 4 check (some do, most don't).

What you're feeling: Mild bloating beginning to develop as follicles grow. Some women feel nothing. Both are normal.

Day 6 — First Monitoring Scan

What happens:

  • Transvaginal ultrasound to measure follicle sizes. Your doctor is looking for multiple follicles growing at a similar pace.
  • Blood test: Estradiol (E2) to confirm the follicles are functioning.

What the numbers mean:

  • Follicles are measured in millimetres (mm). On Day 6, you're hoping for several follicles in the 8–12mm range.
  • E2 should be rising — roughly 200–300 pg/mL per mature follicle eventually, though Day 6 values are much lower.

If on antagonist protocol: Your doctor may add the GnRH antagonist injection (Cetrotide or Ganirelix) today or tomorrow to prevent premature LH surge. This is a second daily injection.

Medication dose adjustment: Based on your scan and E2, your doctor may increase or decrease your gonadotropin dose. This is normal and expected.

Questions to ask at Day 6 monitoring

- How many follicles are growing? Are they similar in size? - Is my E2 where you'd expect it? - Are you changing my medication dose? Why?

Days 7–9 — Peak Stimulation Phase

Monitoring scans every 1–2 days. Most Indian clinics schedule scans on Days 6, 8, and 10 — sometimes adding Day 9 if growth needs closer watching.

What you're tracking:

  • Lead follicles approaching 16–20mm (the target for maturity is 17–20mm)
  • Multiple follicles ideally within 3–4mm of each other in size
  • Rising E2 in proportion to follicle count

What you're feeling: Noticeably bloated. Lower abdominal heaviness and pressure as the ovaries enlarge. Some pelvic discomfort is normal. Sharp pain is not — call your clinic.

Ovarian Hyperstimulation Syndrome (OHSS) warning: If you have high AFC or polycystic ovaries, watch for rapid worsening of bloating, nausea, difficulty breathing, or reduced urination. These can be signs of early OHSS. Report immediately. Your doctor may freeze all embryos (a "freeze-all" cycle) rather than transfer fresh to reduce OHSS risk.

Day 10–12 — Final Monitoring and Trigger Decision

What happens:

  • Final scan to confirm lead follicles have reached 17–20mm
  • If 3+ follicles are ≥17mm and E2 is appropriate, your doctor will clear you for the trigger shot

What you're feeling: Significant bloating. Some women describe feeling like their abdomen is "full." This is your ovaries enlarged from multiple growing follicles.

Trigger Night — 36 Hours Before Retrieval

This is one of the most time-critical moments in your cycle.

What happens:

  • You inject the trigger shot at a precisely specified time (e.g., 11:00 PM exactly)
  • The trigger causes the eggs to complete their final maturation and prepares them for release
  • Egg retrieval is scheduled exactly 34–36 hours later

Common trigger medications in India:

  • hCG trigger (Ovitrelle, Pregnyl): Most common. Standard for most patients.
  • GnRH agonist trigger (Leupride): Used in high-risk OHSS patients. Reduces OHSS risk significantly.
  • Dual trigger (hCG + agonist): Used at some centres for poor responders.

Critical: The trigger shot must be given at the exact time specified. Not ± 2 hours. The exact time. Set an alarm. Missing the window can cause premature egg release before retrieval.

Egg Retrieval Day (Day 14–15 typically) — Ovum Pick-Up (OPU)

This is the procedure most people mean when they say "IVF procedure."

What happens:

  1. 1You arrive at the clinic fasting (typically nothing by mouth for 6 hours before)
  2. 2IV line is placed; you receive IV sedation (not general anaesthesia — you are unconscious but not intubated)
  3. 3The embryologist and doctor prepare in the adjacent lab
  4. 4Under ultrasound guidance, a thin needle is passed through the vaginal wall into each follicle
  5. 5Follicular fluid is drawn out; the embryologist checks each sample immediately under a microscope for eggs
  6. 6The procedure takes 20–30 minutes
  7. 7You are monitored for 1–2 hours before going home

What you feel: Nothing during the procedure (you are sedated). Cramping and soreness for 12–24 hours after is normal. Rest at home for the day.

The numbers:

  • Not every follicle contains a mature egg. Expect roughly 70–80% of follicles to yield eggs.
  • Not every egg will be mature. Expect roughly 75–80% of retrieved eggs to be mature (MII).
  • Example: 10 follicles → 8 eggs retrieved → 6 mature eggs

Questions to ask before egg retrieval

- How many eggs are you expecting? - What sedation will be used? Who administers it? - What should I eat/drink before and after? - When will I get the fertilisation report?

Day of Retrieval — Fertilisation Begins in the Lab

While you recover, the embryologist gets to work.

Two fertilisation methods:

Method: Conventional IVF · How it works: Eggs and 50,000–100,000 sperm placed together in a dish; sperm fertilise naturally · When used: Normal sperm parameters

Method: ICSI (Intracytoplasmic Sperm Injection) · How it works: Single sperm injected directly into each mature egg using a micro-needle · When used: Male factor infertility; poor fertilisation history; low egg numbers; often used routinely

Indian context: ICSI is used very commonly in India — sometimes routinely even when not strictly indicated. Ask your clinic whether ICSI is specifically needed in your case or if it's their default policy.

Fertilisation check (Day 1 after retrieval): Your clinic will call you with the fertilisation report the morning after retrieval. What you'll hear:

"You had 6 mature eggs. 5 fertilised normally (2 pronuclear = 2PN). We'll check them tomorrow."

Normal fertilisation rate: 60–80% of mature eggs.

Days 1–5 After Retrieval — Embryo Culture

Your embryos grow in the incubator. Here's what's happening:

Day After Retrieval: Day 1 · Stage: Fertilisation check (2PN) · What You Should Know: Report from embryologist

Day After Retrieval: Day 2 · Stage: 4-cell embryo · What You Should Know: Some clinics check; some don't disturb

Day After Retrieval: Day 3 · Stage: 8-cell embryo · What You Should Know: Transfer sometimes done here (Day 3 transfer)

Day After Retrieval: Day 4 · Stage: Morula · What You Should Know: Cells compacting together

Day After Retrieval: Day 5 · Stage: Blastocyst · What You Should Know: Preferred stage for transfer — higher implantation rates

Day After Retrieval: Day 6 · Stage: Blastocyst · What You Should Know: Some slow embryos reach blastocyst stage by Day 6

Day 3 vs. Day 5 transfer: Most Indian clinics now prefer Day 5 (blastocyst) transfer. Blastocysts have higher implantation rates because they've "self-selected" — weaker embryos typically arrest before Day 5. However, if you have very few embryos, your doctor may recommend Day 3 transfer.

Embryo grading (blastocysts): A 4AA blastocyst means:

  • 4 = expansion grade (scale 1–6; 3+ is mature)
  • A = inner cell mass quality (A = excellent, B = good, C = fair)
  • A = trophectoderm quality (same scale)

A 4AA is excellent. A 3BB is good. Even a 2CC can implant. Grade is a guide, not a guarantee.

Transfer Day — Embryo Transfer

The embryo transfer is usually the simplest procedure in IVF — but the most emotionally charged.

What happens:

  1. 1You arrive with a full bladder (makes ultrasound guidance easier)
  2. 2You lie on the table; a speculum is placed (like a Pap smear)
  3. 3Under abdominal ultrasound guidance, a thin, flexible catheter passes through the cervix
  4. 4The embryologist loads the embryo(s) into the catheter
  5. 5The embryo is placed in the uterine cavity
  6. 6The procedure takes 5–10 minutes; most women feel mild pressure, not pain
  7. 7Rest for 15–30 minutes at the clinic, then home

How many embryos to transfer? ICMR guidelines and international standards recommend single embryo transfer (eSET) for women under 35 with good-quality embryos. Transferring two embryos raises twin rate significantly — twins carry higher obstetric risk. Discuss this honestly with your doctor.

What you're feeling: Overwhelmed. This is the moment you've worked toward. Some women feel hopeful; some feel terrified. Both are appropriate.

After Transfer: Medications Continue

After transfer, you start luteal phase support — medications to support the uterine lining while the embryo implants.

Medication: Progesterone (Crinone gel, Endogest, Susten) · Route: Vaginal suppository or injection · Duration: Until pregnancy test; continued 10–12 weeks if pregnant

Medication: Estradiol (if FET cycle) · Route: Oral or patch · Duration: Same period

Medication: Aspirin (sometimes) · Route: Oral · Duration: As prescribed

Continue all medications exactly as prescribed. Do not stop without calling your clinic — stopping progesterone early can end a pregnancy.

The Two-Week Wait (TWW): Days 1–14 After Transfer

This is universally agreed to be the hardest part of IVF. You wait 10–14 days for a blood test (beta-hCG) to confirm pregnancy.

Reality check on symptoms:

  • Progesterone suppositories cause bloating, breast tenderness, and nausea — identical to early pregnancy symptoms.
  • Cramping in the first week after transfer is common and does not mean failure.
  • No symptoms does not mean failure.
  • Symptoms are not reliable indicators of whether your embryo implanted.

What to do and not do:

  • Continue all prescribed medications without fail
  • Normal light activity is fine; bed rest is NOT required or recommended (research shows it doesn't improve outcomes)
  • Avoid heavy lifting and intense exercise
  • Do not take a home pregnancy test before Day 10 — early tests give unreliable results with embryo transfer and can cause unnecessary distress

The Pregnancy Test: Beta-hCG Blood Test

On Day 10–14 after transfer, your clinic will order a serum beta-hCG test.

Beta-hCG Result: <5 IU/L · Interpretation: Negative — the cycle did not succeed

Beta-hCG Result: 5–25 IU/L · Interpretation: Borderline — repeat in 48 hours

Beta-hCG Result: >25 IU/L · Interpretation: Positive — clinical pregnancy possible; repeat in 48 hours to confirm doubling

What doubling means: A healthy early pregnancy sees beta-hCG double every 48–72 hours. Single values are less meaningful than the trend.

If positive, you'll have a follow-up ultrasound at 6–7 weeks to confirm fetal heartbeat.

What Happens to Extra Embryos?

If you have embryos that weren't transferred, they can be vitrified (flash-frozen) for future use.

  • Vitrification survival rates: >95% of good-quality embryos survive thaw
  • Frozen embryos can be stored for years
  • A frozen embryo transfer (FET) cycle is simpler, shorter, and less expensive than a fresh cycle (~₹30,000–80,000 vs. ₹1.5–4 lakh for a full fresh cycle)
  • Leftover embryos are yours to decide about: future transfer, donation to research, donation to another couple (with consent under ART Act 2021), or disposal

If the Cycle Doesn't Succeed

60% of first IVF cycles do not result in a live birth. This is the honest number. It doesn't mean something went wrong. It means IVF is not a guaranteed treatment — it's a process that often requires more than one cycle.

After a failed cycle, your doctor should:

  1. 1Review what happened at every stage (eggs retrieved, fertilised, embryos developed, transfer details)
  2. 2Identify any correctable factors
  3. 3Propose a modified protocol for the next attempt

Common next steps after a failed cycle:

  • Changed medication protocol or doses
  • Hysteroscopy to check the uterine cavity
  • Endometrial receptivity assessment (ERA test) if repeated implantation failure
  • PGT-A testing if multiple good-looking embryos have failed to implant
  • Immune workup (controversial, but some clinics investigate NK cells, HLA compatibility)

Ask your doctor: "What specifically did you learn from this cycle, and what would you do differently next time?"
