Okay so I have irregular periods anyway, but this time it's just weird. On the second day of my period, my boyfriend and I had unprotected sex and he accidentally..did it inside me. My period lasted a total of 5 days. 3 days after my period ended I had brown discharge looking stuff on my underwear and when I wiped, but it got heavier and heavier. Now I have blood coming out, but it's not just a light spotting, it's heavy also. This is the 6th day of this happening. The only other symptom I am having is sore breasts. I'm not having any cramps or additional pain. If anyone could help that would be great!
