Dont want to get pregnant

Amber

Okay so I've been with my bf for 2 years and I'm a virgin . Only because every time we get in the mood I back out because I'm terrified of getting pregnant even though I'm on the pill there is that thought in the back of my head that holds me back because I dont want to end up pregnant. And what if the condom breaks or slips or sometimes I feel like im taking birthcontrol and not having symptoms so how do I even know if it's doing its job.
