I bought a few tests at a 99 cent store which is a little different then the dollar tree. They state to put 4 drops wait 3 min for results but not to read after 5 mins. So today is cd 29 and af should be here any minute. So I took the test waited 5 minutes and of course I looked at it for a minute under the light and saw a possible evap line,so put it away a went back to bed. I woke up an hou later and looked at *** again (always semm to do this just in case lol) and there is a line its pink like the control line a pretty dark. I know your not suppose to read it after the time limit but I always go back and look at it and have never seen this. Do you think maybe it could be positive?
