I am in the exact same boat as you girl, I am also 16 and sexually active. I too, have safe sex and yet I have been feeling very paranoid lately. In the back of my head, I've been getting this strange feeling that I'm pregnant just because I've been emotional and had stomach aches a few days ago, and yet there could also be no way. Currently, I'm just eager to get my period, which was supposed to come today but the tracker is never spot on anyways. It's probably just late, as I'm pretty sure mine is, and either way you have options. And so, if your period comes soon (which it probably will) think seriously about birth control afterwards.
He is probably telling the truth, he probably didn't *** inside of you... But Precum CAN get you pregnant. And he can't help that .
