Sorry to hear about your miscarriages. :( I had two, and when I became pregnant the third time, I started to worry, of course. My pregnancies were more spaced out. Anyways, one of the blood clotting disorder tests I asked for was the anticardiolipin antibody test. I believe my doctor ran one other, but can't recall the name. It wasn't the ANA, which for me, had been negative in the past. Also, my lupus panels had been all negative. My grandmother and other family memebers have RA though, and I have unexplained chronic fatigue. My thyroid antibodies are always abnormal, but since my other thyroid testing IS normal, they say not to worry. And sure enough, this pregnancy has been fine for me, I am now 20 weeks. :)
Anyways, while I was waiting for my results for the anticardiolipin antibodies, I was kinda freaking out, and started taking baby aspirin anyways, which honestly, I wouldn't recommend doing unless the doc okays it, but hey, I did it. (the one thing I will suggest, if your result is positive and they want you on 81 mg aspirin, is to go with Bayer Women's, because it doesn't have an enteric coating, which is intended to protect your stomach from ulcers, but the coating has phthalates, which is bad for the fetus. just FYI, so I chose no enteric coating).
But my test ended up neg for that. I guess some women have found that taking the 81 mg of aspirin does help them "hold" a pregnancy, whether or not their tests for clotting disorders are positive. I read that online. They stop it around 10-12 weeks though. Their OB's guide them through this, and normally women only opt to try it when they've had multiple miscarriages with not much explanation.
Anyways, that blood test was also neg for me, like I mentioned. I only took the aspirin for a day or two, then was like, "why am I doing this?" and stopped.
What I DID decide to take, however, and my OB said it was fine, was bioidentical folate, for possible MTHFR mutation, which can also cause bloodflow issues. So I was taking "Solgar 800 mcg Folate as Metafolin". With my prenatal, that put my folate up to 1600 mcg, but my OB said "extra B's won't hurt you." Some women have a genetic mutation called MTHFR, and they either have both or one mutation. I asked my OB about it, and she said that something like 30% of women have at least one mutation and carry pregnancies just fine, so she wasn't going to bother testing me, but if it made me feel better, I could take the extra folate. It did make me "feel" better, so I did. She kinda blew it off, but I did it anyways. I guess having these mutations CAN cause the blood to not flow as well. Since I have so much fatigue, and B vitamins in general help me, I thought that was more reason. So here is the link to the folate:
Basically, when you have the mutation, your body is inefficient at converting the folate you get from food, and also the form in your viatmins!, into something usable by the body. So thus, this "special form." Only a few brands sell this form of folate. Your doc may blow it off like mine, and not want to test you, or they may test you. I personally know women who say they had miscarriages because of this mutation, so I took it more seriously.
I also decided to take this fish oil, to just reduce inflammation in MY body in general (because who knows what they can't test for.....maybe I do have some inflammation/autoimmune):
I actually take 5 at a time. :) It helps my anxiety, I have found, maybe by reducing inflammation in the brain. AND, it's good for developing baby.
Sorry so much info. I put a lot of thought into all this, so I thought I'd pass along the conclusions I came to, and what I did. Who knows, my two miscarriages could have just been random, but I wanted to do "something." I don't think extra folate or fish oil can really hurt (ask your doc of course), so what the heck. Best of luck to you!!!!!!!
