Could I be pregnant???

My boyfriend and I had sex 3 times, 2 days ago, every time we would have sex we used a new Condom and he cleaned up pretty well, however on the last time, the condom broke before and we noticed it when he pulled out. I'm on the pill, however I am sick at the moment and I am taking antibiotics for tonsillitis. Could I be pregnant? I'm getting cramps and I'm meant to get my period today which I haven't gotten yet. I'm getting weird pains in my stomach.

Can someone please help me
