ovulation test ughh??

Nyresha
I took my first ovulation test the 2nd day after my cycle was gone which was June 6th. it was the darkest of the three I took on that day on yesterday & the one this morning. the one this morning was super light compared to the first one and it looks as if my ovulation tests are fading in the test color as I get closer to my "ovulation day" on most of my phone apps. its so confusing and I was wondering if its normal to be that off from your phone app because I was told the phone helps people know when yo start looking but in my case now its confusing me. I think I'll continue taking tests through my "predicted ovulation days" & sees what happens..
