Prenatals and multivitamins

Have any of you ladies experienced skin breakouts when taking prenatals before getting pregnant? 
And have you taken both prenatals and multivitamin? Or stopped taking the multivitamin? Cause I'm taking geritol now plus prenatal. I was just curious if I'm taking to much and I have a sensitivity to something and it's making me break out. It's the worst my skin has ever been even going thru puberty and being pregnant!
