17 maybe pregnant!?

I’ve been on the pill for almost 7 months. I always take it on time and have never missed a pill. My bf and I have sex often and he pulls out way before cumming. My period was supposed to start yesterday and Ik it’s early still but I’m stressing hard. I have off and on light cramps but my period still hasn’t come. Does anyone else use this form of protection? Does it work well for u? I’m so scared.
