I am an extremely regular lady, like when Glow says AF is coming, she arrives bright and early that very day. My husband and I are TTC and this is the very first cycle. AF is now late by two days, I should be on my 3rd day of my cycle right now but she hasn’t come. Boobs are sensitive and veiny, I had a bad bout of nausea yesterday that came on all of the sudden. I tested this morning with FMU and got this on a clear blue, then with the same urine tested with a clear blue digital which was negative. Can you help me out? Is this negative?
