anyone here on medication for nausea their whole pregnancy? I have been taking phenergan (12.5 mg twice a day) since I was 2 months pregnant because my nausea has not been controllable. my ob prescribed it. I just feel too sick without it. now, I am 6 months and I need it more then ever. anyone else had to take this medicine during much of their pregnancy? I hope it doesn't affect the baby but so far my ob says my baby is healthy.
