Does progesterone up the risk of PVT and PE? (Photos)

My PS wants my Mirena out 3 wks before surgery. It contains progesterone, not estrogen I'm getting a TT/lipo to flanks. I have researched Mirena & looked at answers on RS. I'm finding that estrogen seems to be the hormone that can increase the risk of PVT and PE; Mirena does not contain estrogen. I am going to take it out because I want to be as safe as possible and follow what my surgeon has asked, but was wondering why some say it's completely safe and others do not (like my PS). My BMI is 32 so I am also wondering if that combined with any hormone at all, is the issue?
