Glow predicted ovulation day


Hello ladies!!! I am hoping someone can give me some insight on this!

I noticed my predicted ovulation day in Glow was today October 26th, however I tested positive on my at home ovulation test strips Wednesday, October 24th and received a negative ovulation readings Thursday and today (October 25,26th). Is there anyway I can change glow to be more accurate as to when I actually ovulated and not just look at the prediction.

Does anyone have any input or have a similar issue?
