Is this positive?

Cathy • 35 and TTC rainbow and #1 with husband, 37.
I think this might be positive, but its so, so faint. I could use some encouragement! What do you see? Really hoping this is our rainbow! I took it this afternoon on a whim, but I had drank a lot of water in the morning, so maybe my urine was too diluted. Will test again first thing tomorrow morning. I'm 12dpo today, 13dpo tomorrow.
