Woman's Daily Multivitamin to Help Get Pregnant?

Lynzee • Mommy to Ammarie, born on March 3,2016!
A lady at my job told me that she got pregnant after taking woman's day multivitamin. She said she heard other ladies say it helped then get pregnant. 
Has this helped anybody? 
I know I've read if you take Folic Acid at over 400mg, then it can help. 
But I was wondering if anyone had a story about this?
