So my fertile week was Sept 28-3rd. I did have sex on the first day of the fertile window. 3 days ago I had brown discharge, and the following day it turned to pink only when I wiped. I’ve been feeling slightly nauseous on and off and have been abnormally tired for no obvious reason. And today I had this CM. Opinions? Thoughts?

I’m currently 8 days til my next estimated period. I do not have regular cycles though
