URGENT: is this a positive OPK??

Alaina

I started testing on CD16 because Iv never done opks and decided to at the last minute. I almost gave up hope since the lines were getting lighter and I figured I started testing to late well I took the last test today about 2:15-2:30. And got what I believe is a positive. Can any ladies please let me know if they to believe it is? Like I said I’m brand new to this and I feel like I’m getting to excited to quick.
