Help!!

Savanna

I've been spotting on and off for 3 days now and I'm pretty sure its not my period. I'm not cramping or anything like I always do. I took this test today and I thought I saw a line while it was going withing the 10 minutes. I check it about 2 hours later and see this.

Then I check it again an hour later and see this

Wtf!!! Is this a positive or just an evil evap???! I'm so confused. should I have blood work done?
