I'm on the pill but I need help

I'm on the pill and have been for 1 month and a half, we always use a condom but it broke when he pulled out before he came,

(That's what we think) but 4 days later I have been vomiting and stuff, is there a chance I could be pregnant ? I also take my pill everyday and never have missed a day and I take it at the same time every morning. I also have tonsillitis right now, so maybes it's all just in my head? Or the vomiting is from the tonsillitis ??
