Period and TTC

Julia

I had baby #2 in July 2019. I have always had very trackable periods and since her birth the time between my periods are a lot shorter. I used to be a 28 day cycle and now it’s more like 20-21 days. Has anyone had this happen after baby and were you able to get pregnant again easily? I just feel like it’s getting really hard to keep track of when I’m ovulating.
