The worst at 9 weeks (support needed)

Went in for 2nd ultrasound & my worst fear came true: No more heartbeat & baby only measured 7 weeks 😭 
A missed miscarriage...with no symptoms at all. I had been carrying a dead fetus for 2 weeks with no symptoms! We had already announced to family & some friends about the pregnancy.
Doctor recommended D&C and after surgery (yesterday) in severe pain now.
This was our first baby & Im old (40.5) so may be our only chance!!! I cant describe the pain when everyone I know has like 3 kids with no problem. Cant stop crying...!!
