Frustrated and confused??

Meghan • Married to my best friend 💍💍💍 Due August with my rainbow baby ♥️

I am a little lost. I feel like maybe it’s the way I’m taking the picture or something but I feel like as I get closer to ovulating the value should be getting higher, not lower. The pic below is a test from this morning. I’m just not sure. First time using an OPK.
