I Missed My Birth Control Pill On Wednesday And Took

I missed my birth control pill on Wednesday and took it with my Thursday night pill at normal time. on Friday my boyfriend and I went swimming and he precame when we were outside of the water. We got back in the pool and about 10 minutes later he put his penis on my vagina. I haven't missed a pill since then and it is now Monday but im still worried. Help? he never ejaculated.
