Has Anyone had intense itchy nipples????

I have had this intense itch on both nipples for 4 days and I have no idea why it's so annoying . I looked it up and of course said pregnancy I took a test and it's negative. I also am spotting this week which is really weird because I just got off of a 3 week period! I go to the Dr on Monday but I wanted some insight to see if anyone else has had this and what it was?
