please help I'm not sure if it's bfp or just an evap

Zara
The one of the left was taken first taken about 20 mins apart. I'm not sure if the one in the left is just an evap but I left the the bathroom and came back in 10 mins and saw the line so my husband asked me to take another one to be sure and I'm not sure if I had enough pee but came back negative. Do you think it's positive or just an indent please help. I'm very confused I don't wanna get excited but it's hard not to get my hope up!
UPDATE: I guess I'm not pregnant and it was just a defective test I tested again this morning on the same brand of pregnancy test and it came out negative but thanks everyone for your input.
