Was this a chemical or an indent?


This was from a year ago so no worries about hurt feelings by answering one over the other xxx

I got this test, it was pink in person. I got my period 2 days later. I think I was 9DPO (definitely less than 12).

My husbands sperm count and my ovulation came back good- but I’m wondering now about my progesterone. Was this a chemical or just a gnarly indent?
