Pregnant???

I’m 12 days late for my period, I took two tests and both came back negative. I recently just upped my anti depressants from 10mg to 20mg. And I’ve been super stressed with school. But tonight when my bf was eating me out he said it tasted like pennies. And I have been getting cramps here and there. So idk am I pregnant possibly?? Is it just my period being late. Someone help please. And btw we always use condoms and always check them after we’re done having sex!
