Prenatal classes- denied.

I have been on a search for a prenatal yoga or swim class here in San Diego- apparently there exists no such class for a normal woman. Of course, there are plenty of classes about hypnobirthing your baby in a bathtub and classes about why you should eat your placenta/plant it in your backyard/make a shrine out of it- WTF? Are there no classes for a normal pregnant chick that just wants to work out and chill out and not hear about zen-births and hemp diapers? Evidently San Diego is no place for a girl who prefers an epidural and non-placental foodstuffs.
