Digital test...

4 days before my period and took a test this morning I thought it was negative threw it away.... came back later to look at it again.... and I thought I seen something so hubby told me to wait awhile and try another test. I just waited for about 5 hours to pee and dipped a test(pregmate). Within 5 min I seen a LIGHT line. So I dipped a first response and I see another line within about 8 minutes. Then took a digital and it says no... now I’m super emotional and even more confused... so I’m not pregnant?? Or am I.... has anyone gotten an incorrect digital test??
