Prenatal yoga or pilates?

Laine • Mom to 2, with baby number 3 on the way!

Hi ladies! I'm a FTM, the first person of all of my friends to get pregnant and I'm looking for opportunities to meet other expectant moms to share the experience with. I was thinking prenatal yoga or Pilates might be great, but can't really find any. I live in South Loop and work by the Mag Mile. Any ideas?
