How Safe Am I Really?

I'm on my 4th month of taking the pill. I've never missed a day, and I'm always on time taking it. I haven't let him cum inside me yet because I've been really paranoid, but tbh I've been wanting to try that out. Is there anyone that's on or has been on the pill and let your S/O finish inside you, and everything was fine? I know that me asking at all would make it seem like I'm not ready for that, but I'm just looking for other opinions on this.
