Hi guys, im 16 yrs old and i had protected sex with my boyfriend  last march 23. Then after sex, i bleed and my vagina's surface was really painful at that time.. I'm so worried because i still haven't had my period and its already april 4. But i took pregnancy test on march 31 negative and another one on april 2 still negative.. I really need help, am i pregnant or?? Im feeling so worried right now
