Heavy first period after birth

Bleeding after birth is lochia, not a menstrual period, and it gradually changes as the uterus recovers. When periods return, the first cycle may be heavier, more painful, or less predictable than before pregnancy. Breastfeeding can delay the return of periods, but it does not make pregnancy impossible. If heavy cycles continue, possible contributors include uterine fibroids, adenomyosis, endometrial polyps, endometrial hyperplasia, perimenopause, or Polycystic Ovary Syndrome. Ongoing blood loss can contribute to iron deficiency anaemia.

Record the start and end of bleeding, how quickly protection becomes full, clots, pain, dizziness, and whether bleeding occurs between periods. Arrange a review if the pattern is much heavier than expected or keeps recurring. Tell the clinician whether you are breastfeeding, had a caesarean or vaginal birth, use contraception, or could be pregnant. Do not assume every bleed is a period; Heavy Periods provides a related symptom overview.

Seek urgent care for rapidly heavy bleeding, faintness, breathlessness, severe abdominal or pelvic pain, fever, chills, or foul-smelling discharge. Contact a clinician promptly if bleeding continues beyond the expected postpartum recovery, returns heavily after settling, or leaves you exhausted and weak. A positive pregnancy test with pain or bleeding also needs urgent assessment.

Ask whether the bleeding is a returning period or another postpartum problem, whether you need a blood count or examination, which contraception is suitable, and how breastfeeding affects treatment choices.
