Am I most likely pregnant?

Bailey

I took a test this morning and definitely had 2 lines, although a bit faint. I took a test later today and it said not pregnant. I am about 5 days away from my period & I read on the pregnancy test the others might come up negative after “the first pee of the day” until I’m closer to the day of my next potential period. Do we think this test was a fluke or that I am pregnant but I need to wait a few days to test again?
