So I bought a twin pack of these - tested yesterday at 12 dpo and stayed bright white. Test this morning at 13 dpo with FMU (although I was struggling to wee for 10 seconds more line 3 or 4 seconds) and after the regulation 3 mins, nothing to see. A couple of minutes later a faint line appeared and a few mins later (after 10 mins) I checked again and there is a definite line.
Obviously some issues with how I took the test (not enough wee? too long for result?) so this is all just a matter of speculation but wondered if any users of this brand have any thoughts on whether they are bad for evaporation lines or had similar experiences?
It says to discard test results after 5 minutes...I was still busy squinting at 5 minutes as I thought I could see a line developing (turned out I could!)
I can't test again now until Thursday for various reasons so will be in suspense for a few more days but thought I'd fill it with some -obsessive- musings in the meantime :)
