Positive and negative in same day.

I took this test this morning. I would be 2 weeks 5 days based on my lmp. So no missed period yet. I took another test later to make sure and it was negative. The first line showed up immediately, before the urine even got to the control line. I took it because all my ovulation tests have been negative and I thought maybe it was because I was already pregnant. I’m going to test again in the morning with my first void. I know false positives are a thing, but can you get a false positive and a true negative a few hours apart?
