Bleeding occurs with uterine contractions, which worries me a lot. I suspect I might have a gynecological condition and would like to understand the possible reasons for bleeding associated with uterine contractions.

Bleeding caused by uterine contractions is generally due to pregnancy, miscarriage, or ectopic pregnancy. However, it could also result from retained placental tissue after childbirth, placental polyps, or poor uterine recovery, all of which may lead to uterine bleeding. Bleeding associated with uterine contractions might be triggered by external stimuli, fatigue, prolonged standing, or other irritants causing the uterus to contract and bleed. Patients should keep warm, especially protecting the abdomen from cold.
