getting a little scared.

I tested again today and my 12 dpo line is kind of scaring me. I feel like it's lighter than my 11 dpo. 
The top picture it directly after taking them both and waiting the three minutes
And the bottom pic is of twelve and eleven today after eleven sat out all night. 
This picture is right after taking both tests. 
This is right after taking the 12 and the 11 sat out all night.
