Before december the last time i had sex was in june with my boyfriend before i went to college out of state. When i left i didnt have my period at all. I had a pregnancy scare but no symptomsof pregnancy. Just no period. Turns out i wasnt pregnant. I came back for the holiday break and me and my boyfriend had sex. Still no period to showing up. When i came back to school jan. 3 my period still didnt show. But last friday, i had went to the bathroom and i had, what looked like, brown discharge on my underwear. Ever since then its been the same everyday. I use a tampon in case it is my period. But im just not quite sure. What should i do?
