TTC after miscarriage

Ta
First off I want to say sorry to those who have had to suffer through a miscarriage and losing a baby! 
But for those who have had a miscarriage, how long did it take you to concieve again? I believe I had what was called a Blighted Ovum in November. I found out I was pregnant & a week later started spotting which eventually turned into heavier bleeding & was confirmed by the doctor that I had miscarried. 
My fiancé and I have decided to try again. I'm nervous of it happening again & that's all I can think about. But I know I'm ready. Any advice is appreciated!
