Looking for some feedback

Hi 
My husband and I have been trying to concieve for about 6 months I've been off birth control for a year now
I'm 20 and he is 22
I'm very concerned because it's taking what to me feels like too long
My doctor said I shouldn't be too concerned until after a year since my periods and such are regular
But last month it was about 6 days late 
We really want to start a family and I'm just worried I can't have a child :/
