Success after two losses?

This past November I had my second miscarriage (8 weeks), the first was in June ( 6 weeks- blighted ovum). My husband and I have no children so we are extra nervous about being able to have kids of our own. The second miscarriage was extremely devastating to me, but I feel like my body is getting back to normal and we now feel ready to start trying again. I am terrified of having a third miscarriage, even though my OB tells me that odds are in my favor. Does anyone have any advice or success stories after having more than one miscarriage? I am trying to keep my thoughts positive but it's so hard!
