I’m two days late and have taken several pregnancy test. I am not always regular so my period is not the biggest indicator but I have never had an evap line or a false positive. I have two equate tests with lines outside of the window and while looking for a test I just did I found the one in the picture from a few days ago.

I know I need to retest tomorrow. I just need to here some one else’s experience in the meantime. Thanks
