BC question

Taelor
So I take my birth control faithfully everyday! Never missed a pill none of that. ALSO before I ask my question I am very WELL educated on sex and how birth control works. I have been on BC since July of 2016 been with the same person and everything. So today just like an hour ago I was having sex with the guy and he always pulls out and he did this time but NEVER has he ever put it back in after he came he did it this time but only for 3 seconds. So I am a very paranoid person and I was wondering will I sill be good if he did that? I think I am idk. btw I do start my period next week
