TTC too early?

My boyfriend and I have been together for 6 years! He just graduated college and I graduate next year. We have been TTC for about 3 months. We plan on getting married as soon as I graduate. Is it too soon for us to try? Or should we just wait until we are married in a year? 
Oh and I had a miscarriage about 3 years ago, kind of why we put a rush on the baby thing !
