Only 5 weeks but look like 11!

The first time I noticed a small bump above my pubic bone with my first pregnancy was at 11 weeks. Admittedly I am 10-15 lbs heavier at the beginning of this pregnancy as I was at the beginning of my last pregnancy. But it doesn't look or feel like bloat to me (the lowest part that I'm showing by my shorts). Could I really be showing at 5 weeks??
