How long after you were done breastfeeding did it take to stop lactating?

I had some issues breastfeeding and completely stoop around month 6, but I had stopped majorly around 4-5.

I thought I had completely stopped ant drops around 9 monthsish.

But now I'm getting drops again! I'm kind of hoping that pregnancy hormones are doing it, but then again you don't lactate until the baby us born. So thoughts?
