I am now almost 14 weeks, and I'm in maternity jeans. I fit into my normal ones, but the buttons really hurt when I sit down. I say embrace the bump even though right now it looks more like I had too many curries than I am with child :D
I agree embrace the bump and the comfort of maternity clothes.
I am 14 weeks along and didn't start off as a skinny girl. So no one has really said anything but I noticed that pants added too much pressure when I sat down. My wife urged me to buy maternity pants. Changed my life!
