What did I do?? Advice please!!

Hey Ladies,

My period ended about 2 days ago and according to my period tracker, I’m expected to ovulate in 9 days.

However today my boyfriend and I had 4 rounds of unprotected sex & he finished inside of me each time. I took 2 birth control pills leading up to today but I bought them a few months back & idk if they’re expired or not or if 2 days worth of birth control pills are even enough to do anything.

So my question is, can you get pregnant without/ before ovulating? If so, what are the chances of me getting pregnant?
