Should my tests be darker?

I got a faint bfp on Thursday at 12dpo. I tested around 5pm while my daughter was in the bath and forgot about the test for about 40min. I was shocked to find a faint line.

When I was TTC with my son I got my first bfp at 10do and it got steadily darker. My daughter was a surprise and got a dark positive when pregnant with her.

Have u tried the digi again?

That last one looks darker , maybe you ovulated later ?

 

[MollyNorwood]

I would also agree that perhaps you ovulated later than you thought. Either way those lines are darkening so try not to stress about it. wait a day or two and try another digi

First test still isn't very dark but I am guessing that doesn't matter because of the digi? Should I get bloods done?

My testo never got very dark with this pregnancy, I didn't even get a positive till I was 2 days late for af, but got a positive digital like you and I'm now 18 weeks, congrats xxx

My tests from 3 days after af due
