Dang Guai, Heparin, Low dose aspirin, third trimester?

I have antiphospholipid antibody syndrome and am on heparin and low dose aspirin and am currently 35 weeks pregnant. This regime has worked well for me, I had recurring miscarriages previously, this is now my third pregnancy in a row that has made it past 6 weeks, and so far this little guy seems to be doing just fine. Unfortunately, I haven't been and struggle with intense anger and emotional volatility issues while pregnant and for a few months post partum. This is compounded with each successful pregnancy as I have more responsibilities to deal with, current;y my two younger high energy kids.  I went to a TCM practitioner in Victoria BC and he gave me some herb tea packs to use for a week, one of the packages to use daily is dang guai. I know that Dang Guai use in pregnancy is a source of controversy as far as western vs chinese medicine goes, however I'm not too worried about labor starting this early but i am wondering about the blood thinning stuff because I'm already on two other blood thinners. I mentioned this to the TCM doctor and he wasn't concerned about it and thought that it would really help me and be of benefit. I know that you guys deal with my condition, patients who are on blood thinners, and TCM herbs so I'm hoping that I can get some expert second opinions and thoughts. Thank you!
