do you feel the pregnancy vitamins really work? I have not been taking them all along - I know- naughty and am now low on B12 and probably iron too. So I am going to start taking the B12 and am thinking I should go on the prenatals too. Do you find they really give you more energy or is it all just psychological? I am not a big pill taker and am currently taking meds for nausea, and reflux so that will make it about 4 or 5 pills in a day! annoying but I'll do it if it will help. What do you find?
