I had a MC last month 9-13 and I have not had AF return yet. I have three different AF trackers on my phone and each one says my AF is due at different times. one says I'm two day late, the second says it's due tomorrow, and the third says on Thursday. So to be sure I have taken pregnancy two test both were negative. But I have been extremely fatigued and had cramping on my left side only periodically the last two days. I haven't had any signs of AF showing up like I usually do. what could this mean should I be worried? and would you ladies wait until Thursday to take another test?
