she's completely wrong. I have been doing my vest from day one of ttc through early pregnancy and now. the doc said that I'd probably be too uncomfortable to do my vest past 6-7 months bc of being too big, but I am still doing 2 therapies a day with it.
in the beginning while I had the nausea the vest was harder-i threw up alot with it, but its not as if its contraindicated for preg. (the vibrations arent going to cause a miscarriage or upset the baby) some people just have a harder time with it and have to adjust their therapies. but my doc is thrilled that i've been able to stick with it the whole time.
