Normal?

Darker one was taken last night, and the lighter one was taken this morning with FMU. Why would it be lighter 😫 I did give it an extra 2 minutes and got a little darker but not darker then the first one 🙁

UPDATE!!!

Well, I got home and decided to test again. And it’s darker than this morning. So, I think FMU doesn’t work for me lol 🤨
