This is all I got and bunch of recurring miscarriages

I had only one positive pregnancy test and every other miscarriage I had after that happened before I had a chance to check with the test. It would always happen when I was ovulating. Cramping, bloating,. Then I know it's over. Doctors couldn't figure it out. I did research and I asked my doctor to check for the mutations. I am C677T (homo) positive. My levels are still within normal but does that mean the miscarriages can still occur?
