Are you aware of when you ovulate?
Yes I seen a doc they said everything fine..... maybe its not my time.... he even been to the doc.... nothing wrong....
4 years? Have you seen a doctor? Geritol is just vitamins, if you're trying to get pregnant you should already be on a prenatal vitamin with folic acid to help reduce possible neural tube defects in your baby.
If you aren't pregnant after 4 years of intentionally timing sex for pregnancy, I highly doubt just extra vitamins will help you get knocked up. See a doc for diagnostic testing.
