The IVF Process Step by Step — a Patient’s Timeline

IVF feels overwhelming before you start — and surprisingly manageable once you’re in it. The entire process takes three to four weeks from stimulation to pregnancy test, with most of the time spent waiting rather than doing. Here’s what actually happens, in order, with honest timing and what each step feels like.

Week 0: Consultation and Testing

Before any IVF cycle, your clinic reviews or orders: AMH, antral follicle count, tubal assessment, semen analysis, and blood work (hormones, infectious-disease screening required by regulation). If everything’s ready, stimulation begins on your next period. If tests are needed, budget 2–4 weeks. This is also when you ask the questions that matter: protocol choice, expected egg yield, lab technology, costs in writing. Our IVF guide lists the seven questions every couple should ask.

Days 1–2: Baseline Scan and Start

On day 2 or 3 of your period, a quick ultrasound confirms the ovaries are quiet (no leftover cysts) and the lining is thin. If all clear, injections begin that evening. Most clinics use a combination of FSH (to grow follicles) and a GnRH antagonist (to prevent premature ovulation). The injections are subcutaneous — fine pen needles into the belly, self-administered at home. Most women are surprised by how undramatic they are.

Days 3–10: Stimulation and Monitoring

Daily injections continue for 8–12 days. You’ll visit the clinic every 2–3 days for ultrasound scans tracking follicle growth and blood tests monitoring hormone levels. Each visit takes 15–30 minutes; you’re at work by mid-morning. The doctor adjusts doses based on response. During this phase you may feel bloated, mild pelvic fullness, and occasional mood swings — the ovaries are growing to several times their normal size, which is working as intended, not a complication.

Day 10–12: The Trigger

When the lead follicles reach 17–20mm, a trigger injection (hCG or GnRH agonist) matures the eggs for retrieval exactly 34–36 hours later. This timing is precise: too early and the eggs aren’t ready; too late and they ovulate naturally and are lost. Your clinic will give you the exact injection time, often late at night, for a morning retrieval two days later.

Day 12–14: Egg Retrieval

A 20–30 minute procedure under light sedation. A thin needle passes through the vaginal wall (guided by ultrasound) to aspirate fluid from each follicle — each fluid sample is checked immediately for an egg. You’re awake within minutes, resting for an hour, and going home the same morning. Expect mild cramping for a day; most women take one day off work, some take none. Your partner provides a sperm sample that morning (or a frozen sample is thawed).

Days 14–19: The Lab Phase

This is the part you don’t see but everything depends on. Eggs are assessed for maturity (typically 75–85% are mature). Fertilisation happens — either conventional IVF (sperm and eggs together in a dish) or ICSI (sperm injected directly). Next morning, fertilisation is confirmed. Over the next 3–5 days, embryos develop in an incubator — the lab monitors division rates and quality. On day 5, the best embryos (blastocysts) are graded. Your clinic calls with an update: how many fertilised, how many reached blastocyst, and which are transfer-quality.

Day 19–20: Embryo Transfer

The gentlest step in the whole process. A thin catheter places one embryo (sometimes two, though single is increasingly standard) into the uterus. No sedation, no pain for most women — similar to a pap smear. It takes five minutes. You rest briefly and go home. Surplus good embryos are frozen for future use — siblings, or second attempts if needed.

Days 20–34: The Two-Week Wait

The hardest part of IVF is doing nothing. Progesterone support (tablets, pessaries, or injections) continues daily. Normal life resumes — work, travel, light exercise are all fine. Bed rest does not improve outcomes; evidence is clear on this. The pregnancy test (blood hCG) comes 10–14 days after transfer. The result is either a number that confirms pregnancy — or the start of a conversation about next steps, which includes the frozen embryos waiting.

If It Works — and If It Doesn’t

A positive hCG leads to an early pregnancy scan two weeks later, after which you transition to routine obstetric care. If negative, the cycle is over but the journey often isn’t: frozen embryo transfers at ₹40,000–70,000 provide additional chances without repeating stimulation. Most IVF babies are not first-cycle babies — and the couples who plan emotionally for a series rather than a single shot handle the process with less devastation.
