Which prenatal vitamin should I buy?

Hi good luck TTC I hope all goes well, my doctor prescribed Prenate-Elite and those were the ones I took, once I delivered the baby and I went to my 6 week check up he recomended I keep taking prenatal vitamins especially if I plan TTC again soon.. and he said I could buy any store brand that would be less expensive, and just as good as long as they contain what you have mentioned above, I took them before going to bed because they made me a little sick in the morning... good luck
