Quoting Megan Hoffman:" i formula feed"
That would explain why you were menstruating so soon after birth. Hmmm...I don't really have any other ideas other than your hormones may still be out of whack. I did remember that I tend to have hot flashes from time to time in the first year after my kids were born, so that could be a normal thing, I never gave it much thought, figured it was hormones. lol, I blame it all on the hormones. I hope things get back to normal for you soon.
