Is this a positive hpt??!

Stephanie

So I am due for my period tomorrow and I decided to take a test this morning. I did not use first morning urine, and took the test after I worked out. Within the first 30 seconds I just saw what looked like a negative so I just assumed I got a negative and threw it in the trash and then when I got home this afternoon, I took it out and this showed up! Does this mean I am pregnant or just evaporation line or a False positive?
