This month has been an emotional roller coaster. I started having symptoms I never get with pms, but all tests have been negative. I thought I had faint lines on a few different brands, but it turns out they were all indents or evaps. AF is due today but so far the only sign is some light cramping. Usually I get low back pain that tells me AF is about to start. Then this morning I had metal mouth, which I've only had during my last pregnancy. So I went and got a first response just to double check, and still nothing. I will welcome AF with open arms just to end this limbo
