I was diagnosed with AA after 3 first-trimester miscarriages (and no other symptoms such as blood clots in the legs, etc).
For my fourth pregnancy (dd will be 1 next week!
), I charted so I would know when I was ovulating and then started taking 2 shots of heparin daily 3 days after o'ing. Most docs will tell you to wait until you have a positive hpt before begining the injections but research shows that it's not as effective if you wait because microscopic clots can form in the uterine lining and interfere with implantation. After I got a positive hpt I switched to Lovenox, which is a lower molecular weight heparing, and which does not require as many blood tests to measure your clotting levels. I only had to go to the hematologist's once a month for bloodwork.
At 36 weeks I switched back to heparin and continued it for 6 weeks post-partum.
Risks during the pregnancy:
* higher incidence of miscarriage due to clots
* higher risk of IUGR (intrauterine growth retardation, where the fetus doesn't grow properly because it can't get sufficient nutrition from the placenta).
Because of these risks, I saw a high-risk ob every 2 weeks and got frequent sonograms to make sure the baby was growing on schedule.
