Bottom lineThe first period after birth is often heavier, longer, and crampier than usual (sometimes lighter) and may arrive at an unpredictable time, settling over a few cycles - heavy soaking, large clots, or faintness should be checked.

The first period after birth is often different from what you remember. It can be heavier, longer, and more crampy, or it may be light and short - and it might arrive at an unpredictable time, especially if you're breastfeeding.

Common features

• Flow: Frequently heavier and longer than before, sometimes with small clots; for some, lighter.
• Cramps: Can feel stronger or different.
• Timing: Often irregular for the first few cycles.
• Spotting: Some people spot before the period fully establishes.

Why it's different

Pregnancy and breastfeeding reset your hormones, and it takes a few cycles for ovulation and the uterine lining to return to a steady pattern. Things usually even out within a few months or after weaning.

When to seek advice

Check with your provider if you soak a pad or tampon every hour, pass very large clots, have severe pain, or feel faint or very tired. These can suggest heavy bleeding or anemia that's worth treating.

Femora helps you log your first cycles after birth so you know what's normal for you.
