am almost 38 years old. I had my first pregnancy at age 34. We conceived on our own right away and I delivered a full term baby girl. We have been trying to have second child for 2 years. I had a miscarriage a year ago at 6 weeks. We began seeing a fertility specialist 4 months after the first miscarriage. No cause for infertility has been found. We began Clomid and did two rounds of IUI. I got pregnant on the second IUI attempt. I had a second miscarriage in February of this year. At six weeks, a heartbeat was detected, but at 8 weeks there was no heartbeat. The baby measured 7 weeks and 3 days. I had a D&C and the doctor ordered chromosomal testing. The tests showed that there was no chromosomal abnormality. Now my doctor wants to do testing for a clotting disorder. The tests are $1,300 and my insurance won't cover it because they only recommend such testing for recurrent pregnancy loss after 9 weeks and both of my miscarriages have been before 8 weeks. I'm wondering how likely a clotting problem is with having been able to carry a baby to full term previously and with my miscarriages occuring before 9 weeks?
