If I have thin blood, can I still go through with my nose job?

I have had almost 3 blood tests now and each time it has come back the surgeon saying my blood is too thin we need to do another blood test, Is it so they can clarify I have thin blood or will they cancel the whole procedure? I mean loads of people have thin blood right? I eat a lot of fruit and veg, exercise daily, drink lots of water and haven't had any alcohol for over 2 weeks now, I have been eating a lot of spinach lately to help thicken it, I have my next blood test in a few days time.
