Glow originally said my fertile window would be around the 11th-17th of this month. I got a peak fertility result on the Clearblue digital OPK on the 8th. So I logged this into Glow and my fertile window adjusted back a week like I would expect. However, after the Glow update, I just noticed that my fertile window has moved once again and is now saying I should ovulate in the next couple of days. I know I should rely more so on the OPK results, I was just wondering if anyone else has experienced issues with the app like this. This will be my 3rd month TTC, so I feel like I'm getting the hang of the process, just can't figure out why the app keeps changing my fertile window. Thanks in advance for any feedback or advice!
