Bottom lineYes - ovulation happens about two weeks before a period, so you can become fertile and get pregnant before your first postpartum period appears; use contraception even if your period hasn't returned.

Yes. You can ovulate before your first postpartum period arrives, because ovulation happens about two weeks before a period. That means you can become pregnant again without ever seeing a period first.

Why this happens

Your period is the bleed that follows ovulation. When your fertility returns after birth, the egg is released first; if it isn't fertilized, a period follows roughly two weeks later. So the very first ovulation comes with no warning bleed.

What this means for you

If you're sexually active and don't want to conceive again soon, use contraception even if your period hasn't returned. Relying on "no period yet" is not safe.

Breastfeeding and fertility

Exclusive breastfeeding can delay ovulation, and the lactational amenorrhea method (LAM) can be effective, but only if strict conditions are met: your baby is under 6 months, you breastfeed exclusively and frequently day and night, and your period hasn't returned. Once any of those changes, fertility can return quickly.

Femora helps you track signs of returning fertility, like cervical mucus changes, after birth.
