This is my Glo chart, and I mark the beginning and end of my periods. My periods usually last 6-7 days flat. This is last month, then this months.  My boyfriend and I made sure to hit the Peak days cus we are TTC, but have never had much luck due to hormonal imbalances and my periods sometimes being irregular. So I'd always get my hopes up for nothing. But even with weird periods I always track mine down and for the most part when Glo says I have a period I usually start the day or day after it says I'm supposed to.  Well, this recent period I was supposed to have for Oct, I haven't had it and I literally just checked Glo yesterday and seen it said I should be on my period. Today is the 22nd and also (supposed) to be the last day of AF.  I haven't seen AF yet, though.  I'm just a little confused, maybe Glo was a little off? But then again my period is always the same cycle it usually is, but it's been over that. If this is right, my period is late.  Could it be and when should I test? I'm just so scared to get my hopes up for the gazillionth time.. We've been trying for over 6 months. Help? Advice? Please..
