Pullout method question!

Jeena

So am 6 weeks pp, me and my hubby had sex 2 days ago and he definitely pulled out, hes pretty good at pulling it out way before he cums, we’ve married for 4 years and this has been our only birth control method and never got pregnant only when we actually started trying for a baby, but people say that most women are fertile after they have a baby, just wondering if anybody else is the same?
