Missed birth control pill in first week

Hello ladies! I started a new birth control pack on Friday the 7th of April. A few days in I took it like 9 hours late and my period started back up again the next day. Then disappeared the next day. Then a few more days later I took it late again. On April 15 I had unprotected sex three time. Every single time my partner did not cum. We were very drunk so we would have sex and then just stop a little in. The day after we had sex my stomach felt weird and I didn't have a appetite. It is now a week later and my stomach feels like it is turning and cramping. Could I be pregnant?
