Can having sex make you bleed a lot? I had sex two days ago and started bleeding not even an hour ago. I wiped after peeing and it filled the toilet paper enough to wipe twice and it fill it. I called the OB department and she didn't think I should come in because I've had sex... And I'm not bleeding anymore but my hips and back and hurting
