Normal progression?

D

I posted this in the faint lines group as well. Ppl keep saying it’s positive but I don’t want to get too excited bc my lines are super super faint.

Looking for your thoughts.

First one was 10 dpo, then 12 dpo and 13 dpo (today). Af due tomorrow.

Symptoms were strong but maybe less right now. Have intermittent mild cramping on right side, tender breasts and nausea. Scant amount of brown cm twice.
