Your baby at 2 weeks

One dominant follicle grows to about 2 cm and prepares its egg. Towards the end of this week a surge of luteinising hormone (LH) triggers ovulation: the follicle bursts and releases the egg into the fallopian tube, where it can be fertilised for about 12–24 hours.

Your body at 2 weeks

Rising oestrogen makes cervical mucus clear, slippery and stretchy – nature’s way of helping sperm swim. Some women feel a brief twinge on one side of the lower abdomen at ovulation.

Common symptoms this week

  • Egg-white cervical mucus
  • Mild one-sided pelvic twinge
  • Higher libido

Tips & to-do list

  • Have intercourse every 1–2 days in the fertile window rather than trying to time a single day.
  • Ovulation (LH) test strips can confirm your surge.
  • Use our ovulation calculator to find your fertile days.

Check-ups and tests around this week

  • Preconception check-up: haemoglobin, thyroid, blood sugar, rubella immunity

Questions about 2 weeks pregnant

How many months is 2 weeks pregnant?

2 weeks pregnant falls in month 1 of pregnancy, in the first trimester. For medical purposes, weeks and days are more precise than months.

How big is my baby at 2 weeks?

At 2 weeks there is no visible embryo yet; pregnancy is counted from your last period, so the first weeks cover ovulation and conception.

Is it normal to have no symptoms at 2 weeks?

Yes. Every pregnancy is different, and symptoms come and go. Feeling well is not a sign that something is wrong. If you have concerns, or notice any warning signs listed on this page, contact your doctor.
