Positive yesterday; negative today

Yesterday, I had a positive within the 10 minute window of the first response (pink dye, shown below) test. Today there is nothing there. This happened with my daughter four years ago. Took a test, got all excited and went to take one with my husband present the next day and was crushed to see a BFN. That night he had taken me out for dinner and drinks to cheer me up. Then come to find out 2 weeks later, I was 6 weeks pregnant with my daughter. 🤦🏻‍♀️ Has anyone else experienced this?
