Indent?

I’ve been testing for a few days now and getting those bad FRER indents on some tests or negatives on the others. Today I am 11-12DPO I don’t bbt track but did do opk so dpo is just a guess. Today there is a very obvious line but I can’t tell if it has any colour. The indents I was getting you could only see in specific lighting or angles so I knew they were indents. This one is questionable. It’s obviously there but could still be an indent. I guess I’ll have to test in a day or two to see if the colour gets brighter. Fingers crossed 🤞🏻
