Possibly pregnant????

y'all I really be stupid I swear to god.

So my husband and I had sex for the first time since our daughter was born a month ago. We have never used protection or the pull out method before because before we tried for her I was on birth control. Anyways, we are doing the deed raw and as he says he's going to cum I told him to pull out in a panic remembering I'm not on any birth control right now. We think he pulled out on time but we aren't sure PLUS there the precum and whatnot.

I was told you can't take plan B while breastfeeding so I haven't. What are my chances of getting pregnant??
