Is this an indent or start of something?

Help!!! Took this test this morning with FMU. I'm only 6 DPO...I know, I know, super early to be able to tell. Something told me to look closer at the test a little bit later and I swear I thought I saw something. Took a picture and it showed up better. Can these test get indents? Could it be the start of something? Good luck to all testing!
