I'm not sure if it is the way I am carrying, or due to the fact that I started this pregnancy heavier than my last one, but I'm only 20 weeks and already having some trouble with my walking commute (1.5 miles each way). I didn't use a support belt for LO, but I'm thinking I need to invest in one for this pregnancy.

Anyone have a recommendation? I'm a bit confused by the different types (and price points).
