This is my 3rd pregnancy, and the first time I have stayed strictly vegan! Before I went back to being a vegetarian either due to pressures from friends and family or because I wasn't feeling well and couldn't eat all the veggies. However, now I am 22 weeks now and cheese, eggs and dairy products make me want to gag. I never got any kind of morning sickness this time around either which is amazing!!!! Plus, I am far less tired than I have been in the past. It is the best pregnancy I have had yet! Can't wait to meet this vegan baby!

There are other advantages to vegan pregnancy, however:
