If you let an HPT sit past the time limit, will they all end up with an EVAPORATION line? I had 2 dollar tree tests. I took one like Tuesday. It was bfn. I didn't want DH to see it so I put it back in the box and "hid" it till I could throw it away later. I forgot about it. Then I took another test Friday morning. Also bfn. Did the same thing with that one. This morning I went to throw them all away - but decided to look at them both just to see - I was wondering about the EVAP line thing - since I had never noticed one before but so many of you have mentioned them. Anyhow - one test had nothing but the control line. The other one had 2 lines! Now crazy me is wondering why would ONE have a line and the other not. What would cause it to happen on one test but not the other??? Oh - why would I do this to myself??? So of course now I'm thinking the one I took Friday is a possible +... since it was later in my cycle. Even though I know its just an EVAP line cause I didn't look at it again till 24 hours later. Its just annoying seeing that second line (when it doesn't really count!). I never should have looked! So dumb.
