Good evening doctors.. I have this big problem of mine.. I m always thinking about this since the day it happened.. I wanted to ask your opinion if is there any possibility that i would get pregnant? The scenario goes like this.. It was sunday (march 15,2015), my boyfriend and i had intercourse.. I am just so scared because this was my first time that he ejaculated inside me.. My menstration started march 1 but i forgot when was my last day.. I took nordette 13hours after the deed.. 8:32am for 4pills and then after 12 hours i took another 4..I actually experienced nausea, back pain, dizziness and i always feel hungry.. I also had brownish discharge in my underwear after i took the 2nd dose.. After i ate my lunch awhile ago, i felt nausea.. I m getting paranoid and so negative.. What should i do? This is my first time.. Please help.. :-( Thank you!
