Ovulation testing issues. Please help!

Someone please help!! Have been taking pictures of these ovulation strips....does anyone else think I ovulated on cycle day 21? Should I continue to test? I feel like the results are kind of all over the chart...This is really my first month using these consistently and I need some advice.

If I am doing anything wrong please let me know. Husband and I have been trying for about 6 months now. I ordered one step testing strips from amazon and I’m really curious if the strips are not giving me the correct results. Thank you and god bless...baby dust to all.
