I didn't bleed much either and the surgical dressing caught what little bleeding I had. While there was some pain, I didn't use any pain medication other than what I received during surgery. Some people are better able to handle pain than others. If your sensitive to pain, by all means, ask for pain medication but if you don't need it, it's best to avoid it.
I have seen several people after surgery and if your having pain, one of the best times to ask for pain medication is before sleeping. Handling pain while your awake is one thing but if pain keeps you from sleeping, ask for pain medication about half an hour before going to sleep.
