Spotting- Need advice/Thoughts!

Lindsay
I had my period from July 16-July 21st. Ever since the 21st I have had spotting everyday- which I've never had before on any period cycle! 
​The spotting is only when I wipe- none ever shows on my underwear. I also have a lot of CM along with the spotting. 
​Anyone deal with this/ have any ideas  with what it could be? Should I go to the doctor? Could I possibly be ovulating? 
​I'm completely clueless! Thanks for any help!!
