According to glow, AF was supposed to show the 4th or 5th. And I have used glow for a couple months and AF has always showed the time glow said she would. anyways, it's now the 8th and still no AF. Took a test this morning and got a BFN.  I have cramping for a few days. Pms symptoms that I usually have I didn't notice if I had them. Becoming inpatient and don't know if AF is going to show her ugly face or not.
