Tests to understand recurrent miscarriages

This week i have potentially had a second miscarriage, we have a scan to confirm on Friday but sadly we think the worst has happened. 
We are thinking of spending our savings on going private and getting some tests to understand if there is any problems with our ability to hold onto our pregnancy
Has anyone had any tests and were they useful? Thanks so much.
