Irregular cycle post baby

Andreanne

Hey all, i had my first baby in May 2019. I breastfeed exclusively for the first 6 months and on demand after. I got my period back in June 2020, then august 2020 and i have been having a very very long cycle. Last was december 14, i got all the pms for the past 2 weeks but nada. I am not pregnant, but i want to start trying. I am kinds freakin out. Is it normal? Anybody else went through that?
