confused. opinions please!

Okay so yesterday at 11 DPO I got what I thought was a vvvfl. This morning at 12 DPO, I got a flat negative. Anyone have any ideas? Maybe yesterday's was an indent? 
^this was yesterday's with the vvvfl (ignore the black dots, I totally misplaced those😂) 
^ and this one was from this morning. So strange. I'm only 12 dpo and I know I'm still early. I'm not losing faith, just wanting some second opinions. Thanks!
