Stupid question as the answer is wait and try again but, I did a pregnancy test and a 2nd very light line came up just before the 5minutes. It's not easy to see but my husband saw it as well. I took the test in the afternoon and my period is due today. My worry is whether the time I was dipping the test counts within the 5min or not, and whether a line always appears after the 5min whether positive or negative.
Thanks
