Yoga Class

K. • 11/17/16
I'm looking for something to do, and I think Yoga will help calm my nerves at work / about this little bundle of joy. 
I googled if yoga was safe, and it says I should start with prenatal yoga. The place I'm looking at only offers it 2x/ week, and I want to do 4-5x/ week. 
Do I HAVE to do prenatal yoga?
