tanish discharge af 5 days late

hey ladoes long story short AF is usually very in time for me. today makes 5 days late. I took a test at 2 days late and it seemed to be negative. to day I went to the bathroom and had white lotiony creamy discharge. but when I wiped there was creamy discharge with a very very light tan tint to it. .......throughout the last 2 weeks I have been having some off the wall things that don't usually happen. but haven't got my hopes up....but just wandering if anyone had this and what it was
