My wife and me have been on the fertility trail for a long time, both of us are bikram yogis, but I stopped it for a while because the heat is not the best if you have challenges with your sperm count. Didn’t make any difference though and yes she is 10 weeks!
Anyway one of our yoga teachers had a two babies not long ago and she said during her first pregnancy she continued teaching and practicing bikram on a regular basis. She felt great during the pregnancy but the baby was relatively small when she was born. She is healthy no worries. She thought it might have been due to the yoga and stopped practicing and teaching during her second pregnancy. Apparently it made a difference for her.
I am not a doctor, maybe Gabrielle can say something about this?
