Second pink line disappeared

I am 9 or 10 DPO and took a First Response test. Generally when I take them I can see the white indent immediately as it gets wet, but today as it hit the indent it immediately turned Pink before it even reached the control line. I was waiting for the test to dry to show my husband, but by the time it had 2ish minutes the second pink line had disappeared????

I’m so confused we have been TTC for 12 months and this has never happened was it a bad test or could I be pregnant?
