Best prenatals?

Caitlynn
What do you believe are the best prenatals? The ones I've been taking keep making me sick. I still have to wait to visit the doctor in a couple of weeks. But for those of you who have found the best ones give me some pointers please. Because it's becoming a pain everytime I take them I get super nauseated and just want to curl up in a ball and cry myself to sleep. TIA
