In the middle of miscarriage

Amber • 28 yrs old-married for 8 years. Lovebug born 11/3/09 BFP after miscarriage and before AF. Due end of August
I was 7 weeks and due 6/28- my baby's heart stopped beating and I am going through a miscarriage right now. I go tomorrow for an ultrasound to confirm if I will need to do d&c Friday. I'm devastated. I want to try again after this is all over but I'm scared to death. I've only had one pregnancy prior and have one son from it. Are subsequent miscarriages normal? What is the d&c process and recovery like? How long will I cramp and bleed? Will it be hard to get pregnant agon? Thank you for taking the time to read this and help.
