Are all prenatal vitamins the same?

Kristen • -Mommy of a 4 year old & 2 angel babies💜-Expecting my Rainbow in March 2017!

I took Geritol until I got to my 2 week wait. I started taking Spring Valley prenatals with folic acid after ovulation, just in case! I have gotten 3 faint positives in the past 3 days, so maybe this is my Rainbow Baby!

I just want opinions on which prenatal is said to have the most helpful ingredients. Thank you!
