First Timer,

sorry for your losses. We lost our first at 22 weeks a couple of months ago.
When you say you tested mildly positive for lupus, do you mean lupus the disease or the lupus anti-coagulant? The latter is actually unrelated to lupus and causes blood clotting which can lead to recurrent miscarriage. If you have this you may need to be on injected blood thinners as well as aspirin... I may be suffering from a similar condition so I've read a lot about it. I'm not a doctor so obviously this is just advice but it seems like your doctors haven't explained things very well to you... if you like check out hughes-foundation.org and check the diagnosis link.
On the upside if you have this treatment greatly improves your chance of successful pregnancy.

If you like to chat more about it give me a yell.
