Im 17 weeks and I find that my baby bump gets fuller and fuller the more I'm on my feet. By the end of the day I feel like my stomach has stretched 2 inches outward. All this stretching around the belly button is tender. Anyone else going through this?This is my second pregnancy. I never had this problem so early on with my first. So far I have gained 6 lbs which I think is a lot. Sure could use some moral support from mommy's who feel the same way. TIA
