Yoga Yoga has a northwest location off of mopac and burnet, and i know they offer prenatal yoga classes there. i've heard great things about those teachers.
I do prenatal yoga at yoga yoga westgate. Alice is an amazing teacher. Hannah who I think teaches at the north location is currently pregnant as well. She also teaches post natal yoga. I've had one class with Star as a sub but Aluce is my favorite by far. Good luck
