First trimester · 2 weeks pregnant
Week 2: ovulation
An egg is released around the end of this week. This is your fertile window.
In a typical 28-day cycle ovulation happens around day 14. The egg lives for about a day, while sperm can survive up to five days, so the days just before ovulation are the most fertile.

How your baby is developing
- One follicle becomes dominant and releases a mature egg into the fallopian tube.
- The uterine lining thickens again under the influence of oestrogen, ready to receive an embryo.
- If a sperm meets the egg within about 24 hours, fertilisation happens in the tube.
How you may feel
- Clear, stretchy cervical mucus like raw egg white
- A mild one-sided twinge in the lower abdomen (ovulation pain)
- A slight rise in basal body temperature after ovulation
- Higher energy and libido
Ovulation tests detect the hormone surge about a day before the egg is released, which is the best time to try.
What's next
Tests and appointments
No routine tests this week. Keep taking your vitamins and contact your polyclinic with any concerns.
What to do this week
- Have sex every one to two days through the fertile window rather than saving up.
- Keep taking folic acid (1 mg) and potassium iodide (200 µg) every day.
- Avoid saunas, hot tubs and very hot baths for both partners during this window.
Call your doctor or maternity hospital if
- Severe ovulation pain with fever or vomiting is not normal and needs a same-day check.
If something feels wrong, trust yourself and call 103 or your maternity hospital. You will never be wasting anyone's time.
