How long for cycle to regulate?

C

Hi ladies. I’m 8 months pp and breastfeeding. My period returned 2 months ago and I’ve just started my third period today. Each one has arrived over a week early and hangs around for only 3 or so days. I used to be as regular as clockwork with a 29 day cycle and periods lasting 5-7 days. My husband and I are TTC so I don’t know when I’ll be ovulating 🤷🏻‍♀️ when did your cycles return to normal? Does breastfeeding have an effect on regularity? Or is this my new regular? Any help would be appreciated.
