TTC for while.

My husband and i tried to get pregnant for a year and 9 months, and it happened. Then I miscarried at 6 weeks. Now we have been trying to convince and it has been a year since I miscarried. I don’t know what should we do. I don’t know if i should see a doctor or just wait, but I’m tired of waiting. Can anyone give me an advice on what is best to do now.
