Help! I'm going crazy.

The first photo was taken 8 DPO. The second photo was the same test the next morning. Does the timing make it a false positive? This morning (10 DPO) I took a First Response test, and  it is showing negative. I have irregular cycles and take clomid (did ovulate this month), so I'm unsure of when AF will arrive. Day 28 is Tuesday (today is Sunday).
