Cumming inside

Alright ladies, let me preface this by saying I know it isn’t the best choice I could make and I am aware of that but here we are. So I’ve been sleeping with this guy for the past couple of weeks. We don’t use condoms but I am on the pill. He’s finished inside me, a couple of times on accident some I’ve said it’s okay. I know the pill isn’t 100% effective but do you guys think I’m okay? I know the more he does it the more likely I’ll get pregnant and we’ve talked about how I’d prefer it not happen a lot but clearly his pull out game is not strong.
