BioTe Pellet and Surgery?

I’m scheduled for BA and back lipo in 2 weeks . When my surgeon asked me to stop taking my HRT 3-4 weeks before surgery I explained it’s in a pellet so I can’t stop it. Has anyone performed surgery on anyone on BioTe pellets and if so, what is the protocol?Ie., be put on Heparin or Lovenox before surgery, etc. Does BioTe pellet HRT pose less or same risk for DVT ? Thank you!
