my last period was on 2nd nov 2012. i have 40 days cycle. i am getting brown little discharge daily since 7th dec 2012. i had oral sex on 7th dec but the penis did not go inside my vagina . this is my first time. i am still a virgin . i guess some part of sperms just fell on my vagina but the penis did not go inside. i was not worried because i did not have full sexual intercourse. i took the i pill but it was after 72 hours which is of no use i know. but i got some dark brown discharge and it is happening constantly. there is no reddish blood coming out which i always have during my periods. my periods should have come but they are not coming. my breasts are normal and i don t go for urine frequently. but i am really worried if i am pregnant due to that brown discharge. please help me doctor. :(
