Can you help me read these strips

Goat

Hello, I’ve been trying to conceive for about a year now but I’ve only been being serious about tracking my period and using these test strips for the past 2 months. Last month I didn’t have any luck with the test strips, I felt like the lines were displaying real light and coming up negative even though I was supposedly ovulating, mind you this was on another app called “flow” I’m only using glow this month and I think Glow might have it right because I think the lines look dark, what do you think?

Glow says I’m ovulating Saturday and so this whole week until Sunday it says change of conception. I’ve been doing it since Tuesday in hopes of making sure to catch the right day. We are so busy we’ve only been able to do it once a day though. Could you guys help me read these strips, I’m confused because I’m the picture you’ll see with all the strips on the blue case they are like really dark and that was Tuesday and now its Thursday night and the three I just took look lighter? Why would the strips come up looking more negative when I’m closer to my ovulation? I’m just so confused I feel like these strips are bs sometimes- however I must say this is the darkest I’ve seen both lines together which means positive so I don’t know...... any help you guys could give would be greatly appreciated
