TTC for baby #1!

Hi friends! So I got off my birth control back in December, so we haven’t been trying for long. I bought some ovulation strips and have been testing my every day. Obviously, as my first time, I have no idea what I’m doing lol. So, I’ve been looking for a positive ovulation test, and thought I would be having a positive test today as they’ve been getting progressively darker the past couple days, but today my test was lighter than the other days. I’m confused and would love any advice/insight!!
