When did you get your 1st postpartum period?

Kelvin is over 6 months old- OK, he's my 5th kid- you would think I wouldn't wonder about this- but when will I get my period?! LOL
In the past I noticed I would get it around 4-6 months postpartum (I breastfeed). Now, I did read back in my blog and it seems with Matrim I didn't get my period till he was 6 months+1week old. So Kelvin being about that same age now- I am wondering if it's coming anytime now? I feel like I've been PMSing for months LOL

So I'm just curious- when did you get your first postpartum period? I've talked to some women who didn't get it until they COMPLETELY weaned their baby- like 15 months+, that's nuts! lol I wish!!! As soon as I start to introduce cereal and other foods- that seems to be when I start. And then the other end of the spectrum, Mommas who don't nurse- sometimes get it as early as 6 weeks- damn!

She was born in September and I started back "spotting" in March. That was about the time I started her on pureed solids, I noticed. Even with breastfeeding.
