TTC after nuvaring. HELP PLEASEE!!!

So I took the ring out on September 1st. got a regular period from Sept. 4-8. Then didn't get anything but spotting from Oct. 16 to Nov. 8. The spotting was first dark brown then light brown with a little pink and when I thought it stopped I would get a small amount of bright red blood and then back to more brown and pink discharge. I went to the doctors and all they did was take a pregnancy test and that's it. No test or anything. Is it normal to spot for that long?
