Do these looks the same to you?

Okay so I’m taking ovulation tests and I have been for a while. When I used to take them the control line would just be solid dark colored and then the test line would get darker (like normal). Now the control line is not as dark and it’s so hard to tell if it’s positive or not. According to my app I’m not supposed to ovulate for 7 days. I don’t have any EWMC or symptoms of ovulation. Also, I’m taking Letrozole I have PCOS. Please help!
