Sometimes are cycles are thrown off by stress, illness, and other factors. Did you mark the 22 as a positive result? That may be why Glow changed your prediction. However, if it WAS a positive on the 22, it could be that your body geared up on the 15th and didn’t ovulate on the 16th or 17th. I’ve had that happen a couple of times, and it can truly be annoying as it extends the cycle out by however long it took to actually occur.

Thank you for the help! Yes, I use the regular test strips. I had a strong positive line on 2/15 and on 2/22 the line was really dark. I’m technically on cycle day 36 as of today.

Correct. This last cycle it looked like I O twice.

Test when you miss it on the new date. Yes if you ovulated early then the app will move it. That’s normal. Cus glow has a perdition ovulation date but if you do opks and imput them then the app will move your ovulation date so in tail it will move your period date. It sucks happened to me I ovulated cd24 ugh but my period date was still off I started 3 days before it said. I’m usually 26-28 day cycle this time is like 30-32 so frustrating!!

In a normal cycle your period comes 2 weeks after the day you ovulate, which is why your chart prediction changed. Did you take an ovulation test? If so then I would wait a few more days to test for pregnancy!
