Ovulation testing

Whitney
Today is my 33% day of chance of getting pregnant. So my 4th fertile day. The 2nd and 3rd I took an ovulation test and it didn't show I was positive. But yesterday I swear when I looked at my app yesterday was my highest peak day. But I looked a few min ago and it said today was. Hubby already left for work because he works nights so it's to late to do it now and I didn't take an ovulation test today either. But we had sex the last 3 days. so hoping some stayed behind if today really is my fertile day. But both tests the last 2 days showed negative for ovulation. I took them in the mornings to. Is there a better time in the day to test? Also do you think glow could be wrong about my fertile days? When I have my next period should I start ovulation testing everyday to see what the tests say?
