What is my body doing to me 😫

Jane • 26- 👪 1 June 2016 + 👶July 2018
I normally have 21-24 say cycles.
I am at day 28 now. For the last 2 days I've had brown discharge. I never have that. It's not even consistent and only a couple of times when I go to the loo I noticed it. 
I normally get a cramp and AF is there. 
I just want AF to get moving so I can get it over and done and move on to next month.
