Random bleeding

[deadlyrhythm.livejournal.com]

I flipped through the tags and found this VP post but it doesn't quite answer my question so I was hoping you guys could help with my specific situation.

After I had sex with my boyfriend last night, we noticed some blood on his sheets. I assumed it was spotting and we quickly forgot about it. This morning, I went to pee and there was blood in my underwear, lots of blood in the toilet after I urinated, and blood on the tissue I used to wipe. My last period was from April 24-29 so I know it's not my cycle starting. That cycle was a weird one. It was 5 days late and was abnormally light. The blood I'm seeing now is a dark red/brownish color and thin in consistency.

I'm not on any birth control and never have been. Is there reason for me to be concerned about this random bleeding?

For reason's unknown to my gyno, I bleed after sex, quite consistently. It's usually worse if my partner is well endowed down there.

I've only bled after sex once and it was different than this. I'm still bleeding the next day and it's only getting heavier throughout the day. I'm now bleeding like I do during a menstrual cycle. I'm really confused as to what on earth my uterus is doing.
