Confused 🧐 could I have been pregnant?

This a test I took on December 23

This came up within 10 mins.. I got my period 2 days later on cycle day 11 (which is normal for me) I was 8/9dpo

I’m currently 4 weeks pregnant, but looking through old pregnancy tests I remembered this one.

Could I have had a chemical? Does this look positive? Or does it look like an indent/evap? Personally, I’ve never got a indent/evap line with color on these..
