Plan b & birth control

Sooooo... my bf and I have been sexually active for about 2 months now about everyday almost . And I’m on birth control I take it correctly and we still use condoms and he still pulls out on top of that. We’ve had sex about 3 times without a condom , and I was so scared 1 time I asked him buy a “ take action pill “ and he did . And I took it . But i eventually am going to get an iud inserted around October time. But he has never nutted in me before and we both want to know what it’s like , but getting pregnant is the last thing that can happen to me . And I’m just so paranoid . What are some tips to prevent pregnancy or should I just overall not do it ?
