Prenatal vitamins??

First off I have ovarian cysts and I'm really wondering if I start taking prenatal vitamins if that will increase my chances of getting pregnant?
or do you just get told to do it to prepare your body for when you do finally get pregnant.
I never took the vitamins with my first baby but it took me two year to conceive my first son and if taking them will help I would so try it!!
