Danger in getting pregnant soon after delivering?

Jacklynn
So I've heard it takes the body 5 (or 7 I'm not entirely sure) years to fully heal after having a baby. And it's dangerous to get pregnant again. Also that your skin will stretch farther and you'll get saggy unless you worked out post partum😮any input on this? Had my son December 2015 and got pregnant again November 2016. is my family trying to freak me out or being worry warts
