Stressing over opk

This is FMU. but now I’m reading to not use first morning pee which regardless, this test is negative. I took a test yesterday at the same time and had the same results but then tested last night and got an even fainter line. The first picture is from last night before bed and the second is this morning. Yesterday mornings test turned out just like this mornings test. I’m on cd 17 and honestly think I ovulated earlier than what I thought. Like right after my period early. Have any of you all done that and ended up pregnant? I’ve been using opks for a little over a week now. Even if I was going to ovulate within the next day or two, my line should be a little darker than that shouldn’t it? What time of the day should I test?? Thanks in advance y’all.
