Glow sucks

C
So this week glow has really shit the bed for me. First, the first day I get a high OPK on clear blue digital with fmu it tells me my OPK is false and out of my fertile window. Second day I get another high and it says it's false again. Then I got two more days of high, on my 4th day of high today. And today my whole app switched. My fertile week jumped a whole week ahead and my period was expected in two weeks now 3 cycle went from 31 to 35 days... 😳😐 how does glow know this? It doesn't! This is crap, idk we'll see what happens and when if AF comes but like glow is really pissing me off. I'll also enter info and I'll get 5 insights about random shit I didn't enter. I entered my bbt and I get an insight oh you tracked your cm... Ummmm no. Wtf glow
