Two indents??

Julia

Im 13 DPO, I thought I saw a faint line on my test with FMU today but chalked it up to an indent. I had one test left so I figured id take it tonight just to confirm and I think the line is darker and more obviously pink?? Have I gone nuts? Totally possible. TTC after a miscarriage in late August, AF is due tomorrow….thoughts ladies? Top pic is test from this morning, bottom is from just now. Both pics were taken at 3 minutes
