Prenatal pills while TTC

Briana
Is anyone taking prenatal pills while TTC ? I thought it was important to take them while TTC but hadn't bought any and well I had my female exam yesterday she told me even though I've been TTC for a year I should just keep trying a few more months and meanwhile I can take folic acid and prenatal pills once I become pregnant im sure she knows what she's talking about has anyone else gotten different advice or does this way seem right?
