You know it truly just depends on the batch. Some batches you will not even get the faintest evaporation line and some you will get a faint one. All the tests I've taken recently (as in the past 6 months or so) have had evaporation lines. The Control line, I must admit, also appears different then it used to in the past few years I've used these tests. It looks thinner to me. So they might have redesigned their tests.
I got a couple of false + with those
Yes! We are!! :0) :0) :0)
Are you adopting a baby after all?
Good luck to you!!
Tests can develop evaporation lines. That's why you should read them in the time it says to and throw them away afterward so that you aren't tempted to go back and look :)
