positive first response tests, negative clear blue digital

Monica • 👼🏼 👼🏼🌈 👶🏼
Hi ladies, my period is two days late (after never being late in my life). I took a few different hpt leading up to the day of my missed period and got 3 negative results (1 first response, 2 Life brand). Yesterday after 2 days of being late I took a First Response test and got a faint line within 3 minutes, the line got a little darker over the next 10 minutes. My husband and I got all excited, so went to the store to pick up a clear blue digital test and it came back not pregnant. So I took another first response and it came back with a second faint line again. 
Are these lines the evap lines I keep reading about? Thanks in advance!!!
