11 day AF ?

Amanda • Mon, Nov 17 2014 • My husband and I have been married for 5yrs. We`re currently expecting #3 and couldn`t be happier!

I started spotting November 7th. The 13th, AF came in guns a blazin. Idk how much more I can take. I have an appointment with my dr next Monday for an unrelated issue but will definitely be bringing this up. What's the longest period you've ever had? At what point does this become concerning?
