so i am new to this but really need help. i had my period march 14 through 20. march 29 & 30 me & my boyfriend had unprotected sex & he came inside of me about 4 times. april 2 through 5 i got this brownish/dark red discharge & i know it wasn't my period 'cause i wasnt due for another week. it was light but when i wiped every now & then it would come out more but became light again. then april 5 through 7 we had unprotected sex again. my nipples have been tender/swollen for about 2 weeks now & im feeling really bloated/tired. my period tracker says im due to get my period this month in the 20's but i find that to be sort of strange. is it possible that i am pregnant?
