I have the same problem. I cant and dont take prenatals because they make me horribly sick. Some people take them at night and that works, but I cant. I do take 2 Flintstone children vits a day and they work fine. Of course I asked the Dr. first and he said that was fine, alot of women do that. So if all else fails try that and of course ask your Dr. first. Hang in there!!
