Dark enough for 15dpo?

Question

Since I got my first faint line on 9dpo I’m freaking out the line isn’t getting darker. 
It’s a weird question but does it look darker than yesterday (first pic)
Thanks!

Answer

Mmh that not good as it should be darker as control line, or maybe you didn't count your DPOs properly.  Mine at 15 dpo the test line was darker than the control line already

Answer

There is no such thing as appropriate darkness of the test. The test tells you only yes or no.

Answer

To see line progression you should test every 48 hours as that’s how long it takes for hcg to double.x
