i am 12 weeks pregnant and am on quite a bit of medication: Alphadopa 250 mg 1.5 tablets everyday, glycomet 500, thyronorm 75 mcg, folvite, Amway Nutrilite Daily Multivit and Amway Salmon Omega 3. Are all of the above safe for the foetus? Amway products are something I am taking on my own .....is that ok?
