prenatal vitamin?

Em
So, I am 13w and 3d and I have been taking folic acid as a prenatal, but it makes me sooo sick! Just wondering what other prenatals are good to take that may help out with the nausea? Or at least won't make me so sick. I have a history of birth defects in my family with cleft pallet and spina bifida in which folic acid decreases the chances of both significantly.
