This is going to be a pretty graphic and detailed question, so that hopefully someone might be able to help me out completely!
My boyfriend and I had a weekend getaway. My period the first day, and that night of we had sex. Turns out I still had a bit of blood left in me. The next morning, afternoon, and night we had sex again, and each time I bled (but my period had definitely ended by this point) and it wasn't a lot of bleeding though. It was maybe two or three wipes of the toilet paper to clean up the vaginal bleeding until there was no more. The next day after that we just did it in the morning, and this time the blood came out more of that wet version (that liquidy texture that you excrete before your period starts or when you get wet etc). So I thought maybe I was just bleeding inside because he had maybe ripped my skin from stretching it out, since the vagina gets pretty vulnerable right after the period. So I thought it might've just been a bleeding from a cut, since there was also a little bit of discomfort when he would initially put it in.
The last day of that weekend though, my stomach kept grumbling like as if I had to use the bathroom, but nothing would come out. The next day I had diarrhea twice and it felt like I was having cramps. I've read that having sex could cause you to have diarrhea though since the vaginal pipe is right next to the rectum pipe.
And the diarrhea only lasted for that one day. But the next day after the diarrhea, every time I have a bowel movement my vagina bleeds. It was just spotting at first, but this morning when I had a bowel movement, it was more blood than usual that was actually released into the toilet. And it took a couple of wipes to clean up the extra blood in my vagina. I've also been having extra vaginal discharge (I've had yeast and vaginitis before and I'm wondering if it might've returned but the discharge could also just be from the vaginal walls healing right?)
