Sometimes during sex I bleed. This is not from menstruation, this is bright red like I've been cut open type bleeding. It's not a little blood when it happens, it's a lot. I've been working with my Dr. since last Fall trying to figure out where it's coming from and why it happens. He is completely baffled and I'm completely bummed. There is no way to predict when it's going to happen. As soon as the sex is over, the bleeding stops. It's almost like blood vessles close to the surface burst open but I don't understand why it wouldn't happen every time if that were the case. It happens every couple of months or so. I'd love to hear if anyone else has experienced this or if anyone has any idea what could cause it. I will tell you it's not coming from my cervix. My Dr. cannot make my cervix bleed. Dr. keeps telling me I need to get right in there when it happens so they can see where it's coming from. Actually tried it once when I had a morning appointment but we just couldn't make it happen - figures.
