What was your period like after breastfeeding?

I’ve been BF for almost three years and just now stopping. Anyways, I’m just now getting my period back but it’s so wonky. I’m on the pill, so it should be very regular (used to be like clockwork before pregnancy). But now I’ll spot for 6 days, nothing for ten days, and now I’m spotting Again.

Like I only had ten days where I didn’t need a panty liner, why is it coming back again already? When does it regulate itself?
