Chromosomal testing results and reasons for miscarriage

Rebecca
How many of you actually found out the reason for your miscarriages? I just had my second D&C a few days ago at 9 weeks. First one was at 11 weeks with the baby measuring at 8. This time they are doing the chromosomal testing on the tissue as this is my second loss. I was just wondering how many of you who had the chromosomal testing done actually found out a reason for their loss?  The doctor says there's only about a 50/50 chance of getting a result back...which is pretty discouraging. Any feedback is greatly appreciated. I'm sorry for all of your losses. This is such a difficult thing for women to go through. Thoughts and prayers are with you all. <3
