Why does sex hurt more around my period?

Pain with sex that flares around your period often points to a hormonally driven pelvic pain source—meaning tissue and nerves in the pelvis become more inflamed and reactive in the days leading up to bleeding and during menstruation. Endometriosis is a common reason: lesions can irritate nearby nerves and organs, and the inflammatory chemicals they produce can amplify pain signals. Adenomyosis (endometrial-like tissue within the uterine muscle) can also make the uterus unusually tender and crampy, so penetration, orgasm-related uterine contractions, or even pelvic pressure can feel painful around that time.

The “where” and “when” of the pain matters. Deep pain with penetration can be related to endometriosis near the uterosacral ligaments, cervix/vaginal fornix, rectovaginal space, bowel, or bladder—especially if scarring or adhesions have altered how those structures move. Pain after sex or after orgasm can happen when pelvic floor muscles spasm or when uterine contractions tug on sensitized areas. If this pattern is recurring, our team can help map your symptom timing and triggers and evaluate for endometriosis, adenomyosis, pelvic floor dysfunction, and overlapping bladder/bowel involvement so treatment targets the real driver of your pain rather than just masking it.
