So AF is 3 days late according to glow. Normally glow is on point with my period (it sometimes a day earlier or the next day) the only symptoms I have are loss of appetite and sore breast but they don't hurt. I haven't been able to eat a full meal or sip enough water without feeling full right away. I'm not bloated and I've been tired and yawning a lot at work. I took a clearblue digital last week and BFN so could it be af is just late or should I test again?
