Next steps?

Hi, my husband and I have suffered 4 miscarriages since hus VR in July '13 (MMC @ 13 weeks, CP @ 5 weeks, MMC @ 10 weeks, MMC @ 9 weeks). REI has indicated they can't provide assistance as our issue is not getting pregnant, it is staying pregnant. We're scheduled to consult with MFM this Tuesday. I'm worried they will also not be able to help as all of our tests have come back normal and no issues have been identified.

Has anyone been in a similar situation? What, if anything, were next steps? Wondering if we've reached the point that adoption is our only option.
