I'm 17 weeks pregnant and when I first found out I was pregnant I weighed 120 pounds now I am at 112 and all I do is eat. Before pregnancy I was into yoga pretty hardcore and since I can't do all the things I did before because it can be dangerous to the baby I didn't know if my weight loss could be from losing muscle or if it would be something else. I go to my doctor tomorrow so ill ask then but I feel like I should have gained weight instead of losing it
