I just got finished having sex, I was having breakthrough bleeding since May 10 but I couldn’t control myself (TMI) however I was barely bleeding ! Which is weird because earlier today I was bleeding until I got home, showered then it stopped. Does having sex stops the bleeding ?

Bleeding during sex is pretty common, especially on this forum, so no need for the TMI no worries. Sex doesn’t stop break through bleeding

It’s normal and common to have sex while bleeding (period/breakthrough bleeding). As @llunx_ said, sex does not stop bleeding
