Could you still be pregnant?

Sam
This was awhile ago and I think I'm fine, but I'm just wondering this. I was on birth control but stopped because I missed like 5 days. So I went like 2 months without my period. And I was freaking out because I have my boyfriend a blowjob and swallowed then I sucked on his finger and he fingered me. I took 2 tests they both said negative. I started my pills again like last month. I got my period. Is it possible to get your period from your birth control "sugar pills" if your pregnant?
