It's been 7 months since I gave birth to my son. I lost all the weight i gained and I'm back in my size 28 pants, but I've noticed my bellybutton hasn't healed. At 1st I had dry skin in my bellybutton. I washed it then dabbed it w/ a little vasaline. This morning I woke up and it's red and wet. I think it's infected, but I don't know why. What's going on w/ my bellybutton? Is this normal? Should I call my OB?
