Help! ovulation test

Erica

We have been trying for 16 months and I started these ovulation test from Amazon this cycle to save money and according to the app I was supposed to ovulate yesterday. I have been taking these test for about a week now and and this is the closest one I have gotten tonight since but it’s still a little bit lighter than I think the right line is supposed to be. Anyone used these? The line was lighter with my am test

Thanks!
