What causes abdominal pain in the lower abdomen after sexual intercourse during the third trimester of pregnancy?

Abdominal pain after intercourse in the third trimester of pregnancy may result from various causes. Stimulation during intercourse can trigger uterine contractions, which is a normal physiological response; however, overly strong contractions may lead to lower abdominal pain. Additionally, if the pregnant woman has certain gynecological conditions such as pelvic inflammatory disease or adnexitis, intercourse may exacerbate inflammation and cause abdominal discomfort. Trauma during intercourse could also contribute to abdominal pain. For safety, it is generally recommended that pregnant women avoid intercourse in the late stages of pregnancy to prevent potential adverse effects on fetal and maternal health. If persistent lower abdominal pain occurs, prompt medical evaluation is advised to determine the underlying cause and initiate appropriate treatment. Moreover, maintaining healthy lifestyle habits and a positive mental state can help reduce pregnancy-related risks.
