I had a missed miscarriage at 10.5 weeks in April. Like you, I found out at my first OB appointment after seeing a healthy heartbeat at 7 weeks. I was also alone at the time and it was awful. My d&C was sensitively handled although it was very emotional...I was very teary. I recovered well though and got my AF 4 weeks later and as you can see by my ticker I am now nearly 9 weeks pregnant again.....Its awful and you will feel pangs (even now I do, as I would be almost in the third trimester now) but with love and support you will get through it...and there is plenty here to be had!
