2 Miscarriages. Need advice

Anna
I am 29 years old with no living children. I had my first miscarriage when I was 19. I was 16 weeks and 4 days. The doctor checked me and said I would be able to have children in the future. 9 years later I became pregnant for a second time. I miscarried at 7 week's and 2 days. Once again the doctor checked me and said I could still have children. My second miscarriage was 8 months ago and my husband is wanting to try again. I'm terrified to try and have a third miscarriage. Help!!!
