12-13 DPO. Yesterday morning compared to today?! Does it look like the line is getting darker?!

I had a chemical pregnancy last month and I just don't want to get my hopes up. Should it be darker or does this look like normal progression?! I feel like it may be darker than yesterday? I thought I was getting mild period cramps yesterday. Tender breasts (not nipple). Mild nausea (not throwing up).
