first of all i am 19 and a virgin. i am not, nor have i ever, been on birth control. 3 weeks ago (Jan 11th) was my last period and my boyfriend fingered me (i'm pretty sure he had precum on his hand) and, freaking out, i got the next choice pill within 72 hours. i am due to start my period in 5 days but am freaking out that i still might be pregnant. am i just overreacting? i feel like i'm having some pregnancy symptoms, but mostly it seems like it might be in my head. i'm not really sure. i'm totaly freaked! HELP!
