Just a recommendation to all...it worked for me! I started my prenatals about 2 weeks ago, and before that I had no pregnancy symptoms. I did a test, and took my prenantals in the morning with the other stuff and I was very sick at work during day almost until 3pm, well I put them off (only the prenatals) at night and guess......no more nausea! I even took them during the day again for two more days and started to notice the difference. So take this in consideration if you are in the morning sickeness club! Take care!
