Girls! Hello everyone, I just gave birth recently, and it will be 40 days soon. I wanted to ask about my belly, the baby, the baby is not big, but the belly is huge still. Many people say that the belly goes away on its own, without tummy tucks, and stretch marks are another story altogether. How long did it take for your belly to go away? ?? ?
