What to do if i just had my wisdom teeth pulled and was wondering how long the bleeding lasts?

Depends: Stops within an hour if you control the first 3 hours = if you bite firm on cotton over this extraction site, and use ice on the outside of the face next to the extraction site.

Varies: Postoperative bleeding from the removal of teeth may be influenced by the position and number of teeth removed, if the teeth were erupted or impacted, if the teeth were removed due to a chronic or acute periodontal problem, and if sutures were placed. Certain prescribed medications and supplements can also prolong bleeding.
