Week 2 of pregnancy: Ovulation Week

Still no embryo: your ovary is getting ready to release an egg. How ovulation timing varies, when the fertile days fall, and trying without pressure.

Last updated 28 September 2026

What's happening this week?

In week 2 your body prepares to ovulate. One follicle becomes dominant, the womb lining thickens, and an egg is usually released around the end of the week in a 28-day cycle, often later in longer cycles. There is still no pregnancy. If you are trying to conceive, the most useful things now are regular sex around the middle of your cycle, a daily folic acid tablet, and meals that follow a balanced Indian plate. It is easy for timing to take over; spreading sex across the middle of the cycle takes the pressure off any single day.

Baby's development

There is still no embryo in week 2. This is the later part of the follicular phase, the stretch of the cycle before ovulation. Of the follicles that started growing last week, one usually becomes dominant and keeps maturing while the others stop. The follicle is a small fluid-filled sac, and the egg inside it finishes maturing during these days.

Meanwhile the endometrium, the lining of the womb, rebuilds and thickens so that it could receive a fertilised egg. At the end of the week the dominant follicle releases its egg towards the fallopian tube. This is ovulation. In a 28-day cycle it tends to be around day 14, but that is an average, not a rule.

The day of ovulation differs between people and can move from cycle to cycle in the same person. If the egg meets sperm, fertilisation usually happens in the tube within about a day of ovulation, which is what week 3 is about. The days before ovulation matter as much as the day itself, which is why regular sex through this part of the cycle gives the best chance. If it does not, the thickened lining is shed as your next period and the cycle starts again.

Gestational age

The 0.1 mm figure is a rough size for a mature egg, close to the limit of what the eye can see. Nobody measures it in a normal cycle; it is shown only to mark the stage. There is no embryo yet, so any fruit comparison for week 2 has no real meaning.

Your body this week

With your period over, the main changes are in the ovary and the womb: the dominant follicle grows and the lining thickens. Some people notice signs around ovulation, such as clearer, stretchier vaginal discharge or a brief twinge low on one side of the tummy, while many notice nothing. None of these is a reliable guide to fertility on its own.

Ovulation does not always fall on day 14. It varies between people and between cycles, so calendar apps that assume a fixed day can be wrong for you. Keeping a simple note of your period dates over a few months gives you, and your doctor, a clearer picture of your own pattern.

Trying to conceive can bring hope and pressure in the same week, and some couples find that scheduled sex takes the pleasure out of it. It can help to agree together how much tracking you want to do, and to remember that conception often takes more than one cycle.

Symptoms you may notice

Every pregnancy is different - you may have some, all or none of these.

Clearer, stretchier discharge
Some people notice discharge becoming clear and slippery in the days before ovulation. It is harmless. Discharge that is itchy, smelly, green or yellow is different and should be checked.
Brief one-sided twinge
A short ache low on one side around ovulation is reported by some people and should settle within hours. Severe or lasting pain, or pain with fever, needs checking.
No signs at all
Many people never notice ovulation. That does not mean it is not happening, and it is not a reason to worry. Period dates recorded over a few cycles are often more useful than looking for signs.
Worry while trying
Waiting and tracking can make you anxious. Sharing the load with your partner, checking apps less often and keeping up activities you enjoy may help. If worry is affecting sleep or work, talk to someone you trust.

Medical care and tests

  • Daily folic acid

    Routine

    Every day while trying, until 12 weeks

    Keep taking 400 micrograms a day. The neural tube forms only a few weeks after ovulation, so taking it steadily through each cycle means it is already working if you conceive.

  • Thyroid test if you have risk factors

    Only if needed

    Before or early in pregnancy

    India's national guideline recommends thyroid screening for women at higher risk, such as those with previous thyroid disease or goitre, a family history, an autoimmune condition, a BMI of 30 or more, recurrent miscarriage or infertility. Many private doctors test everyone at the first pregnancy visit. If a problem is found, treatment can be started or adjusted.

  • Weight and BMI check

    Only if needed

    Before pregnancy

    Knowing your BMI helps your doctor plan how much weight gain to aim for once you are pregnant. Indian guidance uses Asian cut-offs, where a BMI of 23 or above counts as overweight. Because weight-loss diets are not advised during pregnancy, any changes are best made before conception.

If you have been trying for a long time without success, or your periods are very irregular, talk to a doctor, who can advise whether and when tests would be useful.

Nutrition this week

  • Indian dietary guidelines describe a balanced plate built from cereals and millets, pulses, vegetables including green leafy ones, fruit, milk or curd, and a small amount of nuts, seeds and oil.
  • If you eat them, a portion of dal can sometimes be swapped for egg, fish, chicken or meat. Vegetarians can rely on dals, chana, rajma, paneer and curd.
  • Before pregnancy is the right time to work towards a healthy weight, with gradual changes to portions and activity rather than crash diets.
  • Keep added sugar low and go easy on fried snacks and sweets. ICMR-NIN also advises pregnant women to avoid artificial sweeteners, so it is worth cutting back on them now.

Movement and exercise

  • Regular moderate activity such as brisk walking, cycling or dancing supports a healthy weight while you are trying. About 150 minutes a week is the pregnancy guideline, so it is a useful habit to have in place.
  • Avoid hot yoga and very hot rooms around the time you could conceive.
  • Gentle yoga or stretching can be a way to unwind if tracking feels like a chore, and it is something you can carry on with safely once you are pregnant.

Things to keep in mind

  • Sex every day is not necessary. Regular sex across the middle of the cycle covers the days before and around ovulation without timing it to the hour.
  • Ovulation kits and apps help some people but are optional. If they make you anxious, it is fine to stop.
  • Keep avoiding alcohol and tobacco for as long as you are trying.
  • If you work with chemicals such as solvents, pesticides or lead, ask your doctor and employer about safer arrangements before you conceive.
  • Your partner's habits matter too, because second-hand smoke is harmful in pregnancy.

When to contact your doctor

Call your doctor or midwife the same day if you have

  • Pain low in the tummy that lasts more than a day or keeps getting worse.
  • Discharge that is itchy, smelly, green or yellow.
  • Burning or stinging when you pass urine.
  • Bleeding between periods that is new for you.

Get emergency care now if you have

  • Sudden severe tummy pain, especially with fever or vomiting.
  • Heavy bleeding with dizziness or fainting.
  • Fainting or collapse.

In India, call 108 for an ambulance, 102 for free transport for pregnant women in many states, or 112 for any emergency - or go straight to your nearest hospital with a maternity unit.

If something feels wrong, trust that feeling and call - you never need to wait for your next appointment.

Questions to ask your doctor

  • My cycles are irregular. How can I tell when I ovulate?
  • How long should we try before having any tests?
  • Do I need a thyroid test before trying?
  • Is my current weight something to work on before pregnancy?

Week 2 checklist

  • Keep taking folic acid daily
  • Note your cycle length in a diary or app
  • Plan balanced meals for the week
  • Fit in some activity on most days
  • Agree with your partner how much tracking you both want

Frequently asked questions

When is the fertile window?

The fertile days are the ones leading up to and including ovulation, since fertilisation usually happens within about a day of the egg being released. In a 28-day cycle that is roughly the middle of the cycle, but in longer or irregular cycles it may come later. Having regular sex through the middle part of your cycle is a simple way to cover it.

Is ovulation always on day 14?

No. Day 14 is an average for a 28-day cycle. Ovulation varies between people and can move from one cycle to the next in the same person. That is one reason due dates based on the last period are later checked against an early scan. Treat app predictions as estimates rather than fixed dates.

Can I be pregnant in week 2?

Not yet. In week 2 the egg has usually not been released, so there is nothing for a test to find. If conception happens this cycle, it will be around the end of this week or the start of week 3. A home pregnancy test is most reliable from the day your period is due, roughly two weeks after ovulation.
