I start my period like clockwork, CD27 in the evening. Today is CD28 and I have not started AF yet, not even any symptoms.

I used natural progesterone cream (Emerita) this cycle, but last time I applied it was CD26 at night before bed. I did not apply it yesterday because I was told to stop using it the day I am to start AF.

My question is... is it possible that the use of the cream this cycle has delayed AF? Has anyone else experienced this before?
