How long should i deal with the bleeding before calling my doctor and asking about it?

Now: I think you should call immediately. You did not give a lot of information. Your doctor will need more information that you can share.

Immediately: I assume you meant bleeding gums? Contact your dentist with any issues of bleeding gums. It may be minor issue now but it can be a major issue in the very near future.

Any pain, unusual bleeding, or swelling, should be evaluated by your General Physician (or Urgent Care) or General Dentist, depending on the location of the problem. It's never wrong to seek care.
