My periods always came exactly one month after the birth bleeding stopped. I would typically bleed for around 2-3 weeks from birth & then a month from then my period started. Stayed on point ever since. I always started birth control but not until 6 weeks postpartum. This past time I didn’t go on it until 7 months later.

EBF my daughter got my period 2 months PP
EBF my son and took 6-7 months PP

Breastfed and pumped until baby was 14 months. My cycle came once about 10 months pp then again at 13 months pp and has been here ever since. Once it came back for good my supply tanked and I had to wean my little guy off. Oh and I had paragard placed at 8 wks pp.

Breastfed exclusively period took 2 years to come back for one of my kids. The others were immediately after 4 weeks ppd
