Was I Protected

Hey guys.

So I had just gotten off my period on November 1/2. My bf and I had sex without a condom (I’m on the combo pill) on October 31 and he didn’t come inside me. Later this week we had unprotected sex on the 4th while I was still on my sugar pills and he didn’t finish again. Finally on Sunday at like 3 am we had unprotected sex again. I took my pill at 5:30 am Saturday morning like always but around 1:30/2am Sunday I threw up ( from drinking ) before we had sex, but I took my pill for Sunday before we had sex around 2:30/3am Sunday. Once again he didn’t finish. Was I still protected by my pill during these times? Or do I have a risk of pregnancy now? Thank you.
