As mentioned in my last post: Heparin and low-dose Aspirin *may* improve birthweights but no solid evidence to support this.
You need also consider the potential negative effects of heparin (it can increase her risk of excessive bleeding, thrombocytopenia (Thrombocytopenia is a disorder in which the number of platelets (a type of blood cell) is abnormally low, sometimes associated with abnormal bleeding), osteoporosis, daily injections) in situations of unproven benefit.
So to summarize, I think your wife's physician is practicing good reasonable medicine at this point. I know it is hard--particularly given the loss you have experienced--and obviously, since I don't know your wife--I cannot say without having seen her--but it sounds like she is getting good care.
