TMI yellow sticky discharge

Hey all so bit of backstory to a discharge Saga 3dpo I have a huge amount if white creamy sticky discharge now and 10dpo I just went to the loo and I had yellow snot like discharge and been crampy since the 3dpo discharge but since yesterday 9dpo have had cramps all day still have them today and they are like I have AF there painful. I'm due for AF in 4-5 days. Has anyone had this happen? Never have had yellow discharge like this not that I have noticed any way before AF any one had a similar experience what was your outcome :)

Thankx in advance
