Bleeding for 2+ weeks after Wisdom teeth surgery!?

Hello, I am wondering if anyone has experienced a problem like I am. On July 31st I had a wisdom teeth surgery. It was not an easy one, my teeth were still in my gums and pushing my other teeth. After the surgery I was bleeding a little bit, the problem didn't stop for few days and I went to see the doctor. They couldn't stop the bleeding and so I was put in a dental hospital. I had haematoma in my cheek so the doctors did another surgery to clean my cheek and bruises, also to look if something was done wrong in the surgery itself. They saw that my blood vessels overall are very fragile and do not want to heal. After the surgery I got better for few days and went home from the hospital. After 3 days I yawned and something happened that I started to bleed very very bad, it was impossible to stop the bleeding. I was taken to the hospital. Doctors did several blood tests to see if I have blood coagulation problems, but the tests didn't show any. Since I wasn't healing anyways, they put blood plasma in me to help the healing process. This is the third day after the plasma was put in I am not better, whenever the cotton from my mouth is taken out I start to bleed very bad and it takes a while to stop the bleeding. I am also not from the US but from Europe and I was hoping that you could suggest some ideas what might be causing this horrible bleeding and not healing or maybe a homepage or any kind of information that would help me to figure out what is wrong. The doctors in my country apparently are struggling to find out what is causing this terrible problem.
Thank you for your help and support!

Your condition is rare. If hematollogist can not identify the cause of impaired coagulation , you may have vitamin c deficiency. There are some collagen products, for example , colla plug, if placed in the extraction site and soft tissue is sutured properly,post-op bleeding is none or minimal. Intraoral soft tissue surgery always requires suture to facilitate hemostasis. Smoking and alcohol consumption are contraindicated after oral surgical procedure.
