I am 18 days late on my period, and never had a problem with my periods being late before. I'm not on any type of birth control. I decided to take a pregnancy test on the 16th and it came up (to what looks to me) a very very faint positive. Then I took a second pregnancy test very early morning on the 18th, (to me) it looks like the positive line is darker then the other. I put them in a negative filter to see if they would show up on that, they look positive to me but I would love yalls opinions on what y'all see or think.
