Unprotected sex / birth control

I’ve been with my partner for 2 years almost 3 and we’ve never used any protection but I’ve never gotten pregnant yet, we’ve only used the pull out method ^^ I’m worried if I’m unable to get pregnant since I’m so surprised that I haven’t fallen pregnant within these 3 years? We’re not TRYING to get pregnant but I just feel weird about it that I haven’t gotten pregnant haha

Is this normal? Is anyone else going through the same thing or similar?

I’ve never tried the pill but I’ve been looking into it to possibly try it soon
