I mean I used a condom ......once this time

So what do you think ....I don't mind pulling out. However we pulled out first, then he used a condom the second time then third time he peed and we went again and pulled out. I just got off birth control a month ago cause of depression​ and my doctor won't put me back on ( she even told me to use condoms and said plan b was fine to take). I was on the first day of my fertile week it said on glow and I used plan b last month too so idk how accurate it is. Should I bother buying plan b again or just wait it out. We have done the pull out many times and it has worked well but I have huge anxiety.

So it's Monday this all happened Saturday should I bother?
