Anyone see a very faint positive?

I know it's blue dye but I'm saving my pink ones for 14 dpo. I'm currently 11 dpo and I used opk to confirm.

I'm having some nausea and incredibly sore nipples but not breasts. Neither symptoms is a normal pms symptom for me. I can't tell if my eyes are playing tricks on me. 1 test from FMU. Not ttc but the husband would be thrilled.
