So confused 😩

My husband and I are in the first month of "not trying, not preventing". AF was due 9/1. 9/5 and still no AF. 6 BFN blue dye tests and 1 BFN FRER. My boobs are sore, nipples super sensitive, have to pee ALL the time and my appetite is out of this world. Is my body or my mind playing a cruel trick on me? My cycle has always been like clock work.
