Shoot, mine returned before I stopped breast feeding! It's different for everyone, I guess. I've heard of women going months after breast feeding, with no periods, and others who started up right away after they quit breast feeding, and then the unlucky few like me, who never get that break! Sorry, I know this wasn't overly helpful.....
My period have returned before I stopped breastfeeding both times. After 10-11 months each time, I think.
A friend of mine stopped breastfeeding because she wanted to get pregnant again, but her period didn't return in half a year anyway.
I think often the body does things in it's own way
