Pregnant or not

I'm freaking out a little here. I'm 9 days late for my period, I've taken a pregnancy test that said no I wasn't pregnant. I have been sexually active lately with my boyfriend protected and not, but he never cums in me..ever. But I haven't had a period. I've been late before but not this much. Oo and I started bc almost 2 months ago but I did forget to take my bc 2 times this month...what do I do?
