Conceiving after birth (post infertility)

I think they say 3 months after you’re most fertile x

I don't know the general number but I think your window is not small after you give birth. I am not infertile but it took me over 5 months of active trying before conceiving with my first and I had never been on any contraception before that so it was just my body not having it. After I gave birth I was on the pill for 5 months and the moment I stopped it I fell pregnant even while breastfeeding and no period yet and then after my second we were tracking my cycle very carefully for 18 months and one month we were just a little less careful, I immediately fell pregnant and that with a thrown off cycle that month. That being said, I don't know if there is a difference of people who struggled with infertility and people for who it has been easier but I personally found that my overall fertility stayed high after birth so far

Personally we found i seem to have become more fertile as times gone on. I also have PCOS and told I couldn't have kids. It took us 5 years to conceive our first (no losses either) I then went on the pill, come off to try get pregnant and fell pregnant within 2 months, our first was 16 months at the time. After the birth of our second, I went back on the same pill and again we came off to try and get pregnant and fell pregnant that first month, our second was 2 years 6 months at the time. Im due to give birth to our 3rd in 4 weeks
