Please no bashing ..
My bf an I had sex a few hours ago well after I went to go pee I got a wired pain in my side well when I went to wipe there was blood and it's never happen to me before like ever and it scared me a bit it's been months since I've had sex so Idk
that might be the reason for the bleeding , since you haven't had sex in a few months , and when y'all did y'all were rough . your insides were probably like "ooh shit girl ! what is this , I haven't had this treatment in a minute " lol
