i havent seen my period in 3 months so i went to the doctor and she gave me birth control to force my period down. 4 some odd reason i can remember everything else but not taking this pill. im on ortho tri cyclen. i took it the 1st 3 days and missed it that sunday then monday came and i took 2 pills. i had unprotected sex that tuesday with my boyfriend. and didnt take the pill ever since. so then that saturday came along and i had upretected sex again. but wen we was done and he ejaculated in me i saw brown discharge. so the next morning i saw some spotting. than the next day it was a very light pink than was light red. it lasted just as any other period i would get.. but this is the part where im confused. i was walkin in the train station and had got very dizzy. and i felt as if i was about to throw up. everyday since i had sex with my boyfriend i have been having crazy headaches and sleeping like crazy. i eat almost everything now. im not use to this.. what should i do?? could i be pregnant? i really dont want to be.
