Period return while breastfeeding?

Alexa

I’m 10 PP, breastfeeding my daughter on demand and I think my period might be coming back.

I’ve been moody, eating like crazy, slight back pain and my right ovary has been a little achey. I have endo and have had multiple cysts so I’m familiar with the pain.

When did you period return while breastfeeding? I’m so nervous, i haven’t had a natural period (off of hormonal birth control) in YEARS.

Will it be heavier?
