I have been on lovenox and warferin for 3 1/2 days and my blood test came back a little low (1.75). They want me to go for another pk/inr in 2 days. So they suggested I keep taking the Lovenox and upping the warferin from 1 pill to 1 1/2/day. How dangerous is it if I don't take the lovenox and just continue with the warferin.
