Geritol....Questions! TIA

Deanna
Just bought Geritol today. My period is just finishing up in the next 2 days. I hope this helps us conceive! Read some good things on here from other ladies. My questions for any other geritol users: 1) Do I take everyday or only a certain time in my cycle? 2) How many/day? 3) Can I take with Vitex and Metformin? Any other tips would be helpful! Thanks everyone!
