First Response Help

Anyone have an experience with this?? Ive used the First Response early detection test for YEARS with no issues.

I’ve had some early pregnancy symptoms so despite not starting AF til Monday 4/5 I decided to test last night. It was a bit faint but distinctly positive. I’m going to test everyday until Monday. So I tested this morning assuming the line would be darker and it’s not...it actually took the full 3 minutes to show up too. See pics with dates marked. Thoughts?? Other thought is I had a shorter stream of urine with the AM test vs last night
