So i am on the pill but i had sex with my man and i got scared since we usually wear a condom but this time we didnt .. i got so scared that i went to buy the plan b pill.. i took it 16 hours after intercourse and it has been 2 weeks since then ... i have had cramping which is normal but then i have back pain like i have never had .. i am not supposed to start my period until next thrusday and i know its early but i have taken 3 pregnancy all negative. i also have been really tired but i am also getting over the flu.. I wouldnt mind being pregnant if i wasnt in a long distance relationship with my man . What do you guys think ?
