Im doing it and i love it.. i am 23 weeks and really havent gained weight however i dont think it is from the yoga i think its just me that im not gaining weight. I have a great instructor and it really helps with the stress and crazness of being pregnant. And its a wonderful bonding experience with your baby. I feel so close to my son. A lot has to do with the yoga intsructor, the way she relaxes the class and she knows just the right positions for pregnant women. I highly recomend it. To me its more than physical relief. My mind is co clear and put together after that class!
Im 21 weeks and havent gained any weight as well.started yoga like a week ago.im doing it so i can bounce back to my pre pregnancy body faster.hope it helps
