Could It Be Possible?:$

So we have been trying for our first, Last month my period was very very light and about 6 days late, when taking a pregnancy test it came up with a extremely extremely faint second line barely even noticeable and the one a week earlier came up negative, but now im currently 8 days late on my period.. and i have never been this late. We want to wait until friday to find out, I feel like im getting to excited over potentially nothing:$ ?
