TTC AF LATE

Allycia
I need some insight !! My cycles have always been bang on....now af is 4 days late I have taken 2 hpt both negative, sore breasts, and still having some ewcm. This past month I took a break from charting everything as I felt it was becoming too stressful but now I can't even remember when we bd. I have been taking metformin for about 6 months I was also on Clomid but stopped that 2 months ago... has anyone had ewcm when af was due?? I had blood test done today but the wait is driving me crazy!
