No af & negative tests šŸ˜­

So I'm irregular but my last two cycles have been pretty reugular. Af was due Friday according to my last two cycles. No show. I've been cramping and having back pains for the last week to two weeks. Lots of cm. It changes from milky to creamy. I took a test Wednesday and swore I saw a faint line and kept testing and am visibly seeing the white Evap line. Has anyone else been in this situation??Ā
