First Time Wedding Sex

I’ve been married for two weeks, and I was a virgin. I had begun birth control months before the wedding (I’ve never missed a pill once). Our wedding night, he tried to have seemed with me without a condom, it was only a few minutes (because it was uncomfortable), then we stopped because I was clearly not into not having a condom. He didn’t ejaculate, so I shouldn’t have to worry about pregnancy, right? We used condoms every time after that.

I have a light period on BC, but I read about implantation bleeding? Am I overreacting? We are NOT ready to start a family. I just need some experienced advice.
