You can by-pass that risk by going under general anesthesia, but then you still have the risk of bleeds and hematoma
or hemmorage
or even clots from the c-section site. The best way, acc'd to my doc, to navigate this is to go on Heparin instead of Lovenox because your anticoagulant dose can be counteracted, thus reducing alot of the risk of anti-coagulant-based bleeding at the c-section site.
