Ovulation Testing

Samantha • Grateful mama of 2 💞 surprise baby #3 on the way

I need some insight on this. I just bought some cheap tests to start trying to find my ovulation window. My husband and I have been trying to get pregnant for about 10 months now and my period is about 2 months apart. I track my period and all my symptoms that come along with it. Since we are having a hard time trying for our second child, I decided to start taking ovulation tests to help us a little bit. My question main is will the ovulation tests slowly get darker as I get closer to ovulation? My last period was 5/20-5/24, also my shortest and lightest period this year. I took a test today on a whim and its definitely not positive but it is darker than I was expecting it to be. Any advice on this will help me. I'm very new to ovulation testing and need help! I attached my last period and ovulation test from today.
