Prenatal yoga! Anyone else?

I'm 19 weeks pregnant today and just learned about a family yoga studio here offering prenatal yoga classes! I am aiming for a natural birth and I think yoga would be good to incorporate into my routine to prepare. I also find myself with fears and anxiety during my pregnancy and I think yoga/stretching may help put my mind at ease, along with praying daily and trusting God with my baby and body! I'm excited to try out this class and am looking forward to reaping the effects of being more spiritually and mentally in tune with everything! Has anyone else tried prenatal yoga and did you enjoy it?
