I had been taking a multivitamin for the past few years and once I got a positive pregnancy test I went out and purchased One a Day Prenatals with DHA supplement. Well, I just realized that for the past week (week 4) I was only taking the supplement (it was not clearly labeled) and I never took the prenatal! I'm freaking out. I'm 5 weeks today and am going to start taking the prenatal vitamin. Do you think I need to call my doctor?
