My last period was 2/20 through 2/28 and on 3/9 through 3/11 i had the stomach flu and was vomitting and had diarreha. it is now 3/29 and i still haven't had my period. my breast are tender and hurt. me and my boyfriend showered together around 3/21 or so. we didn't do anything sexual but he did soap me. i was wondering if there was any way i could be pregnant.
