Ok so heres the thing. Im 19, a female . My bf and i had sex earlier tonight around 11 and i woke up around three bcuz of the pain and i had too pee. im late on my period, but i had two periods last month its weird. The second period was bright red and extremely heavy with blood clots *i kno tmi but i just gotta kno* anyway i've been feeling like i have to burp or pass gas. I burp a lil but thats it. Any ideas of what it might be. Its going away a lil right now. Its kinda going all over my belly now its weird. Any ideas of wat it could be?
