Breastfeeding and Fertility?

How soon did you start TTC while breastfeeding and how successful were you at it?

How soon did AF come?

I have so many questions but I can only find little to no personal experiences!

I just had my LO in December and I am exclusively breastfeeding. I eventually want to ttc (not any time soon), but I don’t know when my fertility will come back.

Thanks!
