How accurate is glow at calculating periods?

Question

Hi Guys,

I've started using glow last month when I had my period.

It calculated this month's period for February 17th. No period thus far!

Does it need at least 2 period cycles tracked to be able to predict the next period cycle accurately?

I'm confused! Any explanation would be appreciated. Thanks in advance! Enjoy your day ladies!

Yours,
Angie

Answer

Mine almost always hits the days glow shows. I think last cycle though it started a day early and ended a day early

Answer

My period is always way off, 6-7 weeks in between, but glow has managed to almost always predict it now! And when it says I'm ovulating, I almost alway have symptoms of it! It took me 3 cycles for it to be accurate tho!

Answer

It started being spot on after 2 cycles

Answer

I would say so yeah u need a couple months on this for it to be as close as it can.. the app can't give u a correct date but will be closer each time u use app... x

Answer

I think the more data you put, the more accurate it'll be. Glow is always off give or take a day or two. So no big deal for me. Good luck.

Answer

You should be able to tell how accurate it is. Based on your last period should you have gotten a period on the 17th?
