Very Faint line?

Not sure whether it's my eyes playing tricks on me or a very faint line? Tested yesterday and this morning as I'm inpatient! I've had no pre period pains which I normally have and today should be the first day of period... husband thinks he can see the lines too!

First picture is the original

2nd I made black and white and you can see a line....

3rd is the second test in black and white
