question

I had unprotected sex twice in the past 12 hours and the new birth control that I am on makes it to where I only have a period once every three months. I also started new medicine for anxiety and I am not sure if the new medicine will or had an effect on my birth control. I am approaching the first period of the pack and I am just kinda worried about an uh-oh moment. He told me that he didn't cum, at all. And I do know that birth control makes it to where you don't ovulate or release an egg but I am still worried can anyone put my mind at ease please and tell me I am just over thinking this
