The short explanation
It can be normal for periods not to return for many months while breastfeeding, especially if you feed often, including at night. Breastfeeding hormones can pause ovulation. When feeds become less frequent, or solids are started, periods often return. It is still possible to ovulate before the first period comes back, so pregnancy can happen. If you have had sex without contraception, a pregnancy test is sensible.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- If you are not breastfeeding, or periods have not returned months after stopping, it is worth seeing a doctor.
- Thyroid problems, weight changes, stress and some hormone conditions can also affect periods after birth.
- Contraception choices that suit breastfeeding are available; a clinician can discuss them.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell why your periods have not returned or whether you are pregnant. A test and examination may be needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is it normal for my periods to still be absent?
- Could I be pregnant even without a period?
- What contraception suits me while breastfeeding?
- When should I be checked if they do not return?
