C.M.
I was constipated and gassy the first part of my pregnancy.
I started practicing food combining and eating a lot of raw fruits and veggies (i mean a lot) and the constipation and gas went away! As a snack I ate frozen bananas blended with coconut water and walnuts (my fav). For dinner I ate veggies and meat or veggies and a starch.
Hth!!
