i'm 17 and have currently been dating my boyfriend for a bit over one year. so we've been pretty sexually active.

heres the thing:
i had my last period on November 9 till the 13th.
then on the first weekend of December, we had unprotected sex (Dec. 6)
i had given him a blowjob before we had sex, and he came. but didn't go to the bathroom afterwards.
we had unprotected sex a couple minutes later and i'm worried about the precum.
i was supposed to get my period a couple days afterwards. but i haven't gotten it yet. I don't know if i was ovulating or when it starts&ends. or if the egg is even fertile a couple days before an expected period.

could anyone please let me know if i could be pregnant, asap? or what the chances are?

and does thick discharge have any importance on pregnancy signs, or period signs? sometimes i get it thick, and then the next time i go to the bathroom, it's not there...

thanks.
