Ptracker VS Glow

So, before i found out ablow Glow, i was using the Ptracker app... Because i was unser how to really navigate, and use Glow i kept and log on Ptracker as well as Glow now. With that being said. Glow is telling me im 6 days late. Ptracker is telling me i have 2 more days before my period starts. Normally a week before my period. My breast are sore my lower back is killing me,and all i want is sugar. The cramps are unreal (thank you endometriosis) my stomach hurts so bad all i can do is cry... All of that to get to right now... I don't have any of the normal preperiod symptoms. Theres this empty pit feeling, that every time i eat it starts to feel like a bird trying to fight its way out of my stomach (doesn't hurt just oddly uncomfortable) thoughts?
