New pregnancy?

I know this is probably a long shot but I’ve been tracking my hcg with pregnancy tests after my miscarriage, following till the line is gone, it never completely went away but my test seems significantly darker than yesterday’s. I’ve also been getting positive ovulation tests for about 3 days. So I’m thinking I’m just ovulating but I’m just confused as to why it seems darker. I will include pictures and of course I’m still gonna test till there is no line.

Yesterday’s

Today’s.

Both are also fmu.
