I been taking over the counter once a day prenatals with the dha.. I also got a prescription from doctors for prenatals? I feel safer taking the once a day pill becuz it comes with 2 pills seems like more . Or should I take the 1 pill prenatal a day the doc gave me?????????? I feel the 1 pill prenatal isn't enuff.. so I have been taking the once a day prenatal pill with dha..
