Am I pregnant?

So I've been on birth control pills for almost 2 years and recently stopped getting a period because of it. My OB was not concerned about it and said that I am still protected from getting pregnant.

My boyfriend and I had sex many times when I went home for break from college and we didn't use a condom like we usually do but he never finished inside of me.

Over the past few days, I have been extremely hungry, bloated and my breasts are extremely tender. Is it possible that I could've gotten pregnant?
