Just saw this thread. Not sure if this is still something you are on (I saw from another thread that your dr identified a thyroid issue for you too). BUt i thought i'd share in case it helps... I also had blood tests (after two complicated m/cs) showing i might have a higher chance of clotting in pg. Dr told me to take low dose aspirin while TTC and, once i got a BFP, to continue with it until 37wks pg. (He said the plan is usually to take the aspirin until 12 wks or all the way through pg). For me, he also got me to start on injections of blood thinning medication as soon as i had my BFP (so at 4.5wks) which I am on until 37wks also. Don't know if that's what has made the difference for me this time but I am still on both kinds of blood thinners... until SUnday when i'll be 37wks pg.

I hope that the drs can help with the things that have shown up on your blood tests and you can get that sticky bub you dream of...
