I'd been searching for exercise groups too....but none that I heard of. Finally, did some research on the net and bought myself a Yoga DVD - Prenatal Yoga With Shiva Rea. You can buy it from Virgin. I'm liking it so far, they have variations for diff trimesters....a lot of stretching, and a bit of Kegel exercise added in.
Sadly, there are no exercise groups. There is a yoga instructor available who is willing to take pre natal yoga classes. You can find the details @ http://rhythmoflife7.org/
Please let me know when you copy the email address so that I can remove it.
