Not trying, kinda preventing

So I got pregnant in October but miscarried in December. I was on pill when I got pregnant but since the miscarriage i haven’t been back on pill.

We have sex around 4 times a week, sometimes twice in a day. He doesn’t cum inside me though, always pulls out sometimes not very well.

If it happens it happens, I’m not trying to work myself up about it to much.

So what’s the possibility of me getting pregnant?
