Positive test the day after?

Hi all, I took a test yesterday, and saw that it was negative. I was gutted as we miscarried in August 2023 and been trying ever since. I'm now 5 days late, and haven't got any sign of a period. I fished the test out of the trash (crazy lady energy!) and now it has half a line in the positive box. Anyone had this before? Am I pregnant? I will get another test after work, but I just wanted to hear your thoughts?
