what's happening in your body
Estrogen and luteinizing hormone surge mid-week, triggering ovulation. Some women feel a brief twinge on one side of the lower belly or notice slippery cervical mucus.
gentle tips
- Try to time intimacy with your fertile window if you're trying to conceive.
- Skip hot tubs and saunas — overheating can affect sperm and egg quality.
- Keep up the prenatal vitamin and folic acid daily.
- Get 7–9 hours of sleep — hormonal cycles run on rest.
what to expect next
Next week the fertilized egg travels through the fallopian tube while dividing rapidly. You won't feel anything yet.
