AF a no show?

Ashton

So my cycle is normally 27 or 28 days never any longer. It has been 26 days before. AF is supposed to show today and so far NOTHING. I have no spotting and watery CM with not even a pink tint. Im am praying for her not to show her ugly face. Been ttc for 12 months and have an HSG procedure scheduled for next week. Fingers crossed!!!!
