Sex after a C-section and bleeding: what to know

Bleeding after sex following a C-section may be postpartum bleeding or irritated healing tissue, so pause sex and seek advice for heavy or repeated bleeding. A Caesarean incision is in the abdomen, but the uterus, cervix and vagina still recover after birth. Penetration can aggravate dryness, tenderness or a healing vaginal area.

Postpartum bleeding comes from the uterus and can continue after a Caesarean birth. Activity may make it seem heavier for a short time. Blood after penetration may instead arise from a vaginal tear, stitches, cervical irritation, dryness or infection. The abdominal wound can also feel sore when positions stretch the body, even if it is not the source of blood.

A history of pre-eclampsia or other pregnancy complications should be included in your review, especially if you feel unwell or have high blood pressure symptoms. Bleeding after sex alone cannot identify its cause.

Stop penetrative sex until bleeding and pain have settled and a clinician has advised that recovery is progressing normally. Use pads rather than tampons while postpartum bleeding continues. Note when bleeding starts, how much there is, whether it follows sex, and whether you have pain, fever or discharge. When cleared to resume, choose positions that do not press on the abdominal incision, use lubricant if needed and stop if symptoms recur. Postnatal physiotherapy may help with pelvic discomfort, scar mobility and graded return to activity.

Get urgent help for heavy or rapidly worsening bleeding, faintness, severe abdominal or pelvic pain, fever, chills, a foul-smelling discharge, breathlessness, chest pain, or a wound that becomes increasingly red, swollen or draining. Contact your maternity team promptly when bleeding after sex keeps returning, starts after postpartum bleeding had stopped, or is accompanied by worsening pain. Do not wait for a routine check if you feel acutely unwell.

Ask whether the blood is likely from the uterus, cervix, vagina or incision-related strain; whether your wound and pelvic tissues are healing normally; when sex is suitable; and which symptoms require emergency care. Mention your delivery date, bleeding pattern, pain, medicines and any blood-pressure concerns.
