Hi!....difficult, very difficult.
First question is, have you got VWD?
For
1) Heavy bleeding
2) one test + for VWD
Against
1) 2 recent tests neg for VWD
On balance one cannot commit oneself either way.
Second question is, what is causing your heavy bleeds? I have looked in your past postings and cannot find an answer.
Endometrial Ablation,as suggested by honky-tonk MIGHT be an alternative depending upon the cause of your heavy bleeds.
My advice: go to see your GP and quite politely put the position to him and ask if a second opinion would be helpful. Don´t barge in and tell him that the medical profession are a load of w@nkers, as some ABers would do, as hat would just put his back up.
Difficult problem, keep me informed.
