Why does glow have my period comming.early???

Question

I am a constant 27-28 cycle day girl. This month according to glow im suppose to start day 26th? Does anyone had this happen to or know why the app does that??

Answer

AF is due 12-14 days after ovulation, no matter how long your cycle typically is. The thing that changes your cycle length is the number of days before ovulation. So if you entered data that would indicate you ovulated sooner than normal, i.e. a positive opk, fertile cm, or had a bbt spike, then the day your period is due would change.

Answer

That's so strange sooo are we suppose to go by app or.number of days. Lol im so confused

Answer

My glow did the exact same thing this month! The date of my last period was 3/6 and a few days ago it switch all of my days around and has me staring my period 3/28, when originally I was supposed to start 4/3(which would be normal for me).

Answer

Mine did the same I'm supposed to start on the ninth and it changed it to the second now

Answer

Not sure I'm still trying to figure out how and why it told me the wrong ovulation days. I was taking ovulation test and I took it when glow said and it was at the end because the lines faded more and more
