pulling out vs not

i dont know if this is the right group but imma just post this here:

so i’m on the pill, and i’ve been taking it regularly and without incident for a couple weeks. knowing that im protected, but not 100% protected, ive been weary about letting my bf finish inside me. i would like to try it one day (it seems hot) but i also dont want a baby at all.

so the question is: should i try it and trust my bc will control birth, get a plan b after, or just not try it at all ?
