Never getting pregnant? 😳

So I've been dating my boyfriend for about 2 years now. I've taken BC (birthcontrol) since I can remember but there was a year gap that I took to not take the pill. My boyfriend loves to creampie,(when a guy cums inside of you.) since I got on the pill. When I was off the pill he used to cum inside me all the time for that whole year basically. But I didn't get pregnant at all? I'm terrified because I want to have kids one day and just realizing that makes me wonder if I'm not able to have kids!
