I have had 3 last 1st/early 2nd trimester miscarriages after the relatively uncomplicated birth of my daughter. They ended at 15, 13, and 13 weeks. In all cases, the baby looked great at the 12 week scan, measuring right for dates and looked just fine. I have ahd a whole host of testing done - everything you can think of! The only thing that came back was being compound heterozygous for MTHFR mutations, but with normal homocysteine levels. Other than that, nothing else. My last pregnancy I took extra folic acid, B vitamins, and baby aspirin for good emasure. Now I have gotten a surprise BFP and my doc is talking about Lovenox (low dose). Maternal fetal medicine says NO WAY its too risky without having a diagnosed blood clotting disorder, but my OB and RE are willing to put me on it. I'm concerned about the risks (to myself, I know it won't affect the baby). Is it all that risky? Could it help in my situation? I dont know what else to do but really want to have more kids!
