Maybe local pregnancy resource center would know where to refer you. They could at least get you in for an initial visit. Try Woman to Woman pregnancy resource center in Denton dentonprc.org or ###-###-####.
If the reason you had miscarriages was because of low progesterone levels (which is why I had one), you'll need to get a prescription for progesterone ASAP. It's worth full price at an OB for that first visit. I use Dr. Tovar at North Texas OBGYN Associates in Lewisville. Any of the docs or the nurse practitioner in that office are great. Just tell them your situation and your history of miscarriage and they should get you in right away.
Good luck!
