Birth control and cumming inside

I had sex yesterday and my boyfriend came inside of me. Idk why he would do that I really wish he didn’t cus it would save me so much paranoias. Anyways I’m on birth control. I take it everyday at 12. I’ve never missed a day or taken it late or anything. However, this is the first month I have started but I’ve heard it effective after a week of using it.

Do y’all think I’m okay? In the past I’ve taken 2 morning after pills so I’d rather avoid that. I think I’m fine but I’m just gonna get so nervous and worked up. Someone please help
