Is this normal?

I took 2 tests, one yesterday one today. They’re both very faint but shouldn’t it have got darker? It looks like maybe a lil darker but I can’t tell... what do y’all think?! I don’t wanna go through another heartache :( already have had 2 chemicals. Also I’m 12 dpo today, 2 days away from period. (Top pic from yesterday, second from today, bottom pic is both)
