im on a few coz my sis is a natropath....
im on a Natal multi, zinc, ovarianne, progesterlift.
dh is on zinc and tribulus.

we haven't been preg yet.

my sis said to be careful of the over the counter vits because they don't always have a very high level of the right vitamins in them. i get the practiconer(sp) brands from her. you can only get them through a natropath/nutritionist/practiconer of some sort.

good luck
