Is it easier to get prego pp?

Hey mammas I’m just wondering is it actually easier getting pregnant postpartum (6weeks) ? My fiancé and I had sex last night and he didn’t pull out(is what it is) however I had a reaaallly hard time conceiving babyboy like a year hard but I also found out when I was pregnant I had untreated chlamydia (sorry ew) and I read that can make it hard to conceive and I got it treated soon as I found out. Also I think I am or was ovulating two days ago for three days I had super stretchy thick discharge
