I had a terrible time with prenatal vitamins. Or any vitamins for that matter. I take TwinLab Pre-Natal vitamins and have had the best luck with them. They are capsules, but they are the only vitamins I can tolerate. I've taken them for years, even after having my kids because every other one I've tried makes me ill. You can buy them online or at most health food stores. Good luck with everything.
