This is so embarrassing

So yesterday I was with my boyfriend and it started raining.. so we stayed at a hotel for a few hours.. We had sex but not too rough either but I was bleeding a lot.. I remember specific positions I felt a lil pain under my stomach but nothing too bad to stop having sex. This isn't our first time, this never happened.,When we turned the lights on.. seriously the sheets were so bad. it looks like we killed someone. all the sheets and a pillow. I wonder what they will  think when they clean the room lmfaoo ! I couldn't stop bleeding and I had crazy cramps lastnight. I know it's not my period. Idk what to do, maybe get a pelvic exam?
