Second miscarriage. 😭😭

I had a miscarriage at 2 weeks back in 2014. And I just had another friday, at 8 weeks, 4 days, that resulted in a d&c. I have a follow up appt the 30th to talk about everything. But we want to keep trying. How many of yall had miscarriages then had a healthy birth? How long did it take? Did you find out what, if anything, had caused the miscarriages?? I'm so worried I won't be able to have another baby. 😭😭
