Opk test analyzer wrong?


Ok, so my ovulation date on glow used to say it was due August 3rd and that my fertile window started tomorrow. I took a picture of my opk in the app and it said that it was positive today. Now it’s changed my calendar and saying I ovulate tomorrow and that I have a high chance of getting pregnant at 33%. Some background...

yesterday it did say that it was negative but I could start trying. Today I have been cramping a bit and my boobs have felt tingly and a bit sore so I felt ovulation had to be coming soon, but not this soon. First month doing opks but this doesn’t seem right... what do you guys think?
