TTC after misscarriage

I started using Glow in July of last year and found out i was pregnant in November. I was beyond excited and couldn't believe it. My SO and i had been trying to conceive for over a year before that. Unfortunately on January 5th we went in for an ultrasound only to find out that our baby's heart had stopped beating around 8 weeks. It was very debasting. I had to have a d&c 11 days later, the day after my 21st birthday. I would really like to start trying to conceive again soon but my doctor said i should probably wait atleast 3 months. Although i don't mind waiting i'm anxious to start already. BUT im also afraid of getting pregnant and having to go through this again. Anyone have good luck trying to conceive after a misscarriage?
