Thinking about our baby boy

Why didn't I push harder for testing after my second miscarriage? If I would have, I would probably still be pregnant with our baby boy. I wouldn't have had to go through this for a third time and would never have to be labeled a recurrent miscarrier. I understand that there could be other other problems and this pregnancy may not have worked out either. But from what I have found out if I had only known about the MTHFR and Factor V Leiden blood disorders we could have done injections and would still have a growing healthy baby. It makes me so sad to think that this could have been prevented. It really could have, if I had only pushed for testing after the second loss.
