Pregnancy Week 3

The very beginning — here's what's actually happening.

👶 Your baby this week

The fertilized egg divides rapidly while traveling to the uterus, then implants in the uterine lining.

💛 How you might feel

Most people feel nothing. Some notice light implantation spotting around day 6–12 after ovulation.

✅ This week's to-do

Keep taking that folic acid. Avoid alcohol from here on if you might be pregnant.
