OK, should be 12dpo today. I've been testing with FMU since 9dpo and haven't seen the tiniest hint of anything until this morning. The problem is that it's pretty hard to see with my naked eye and I can't even be certain what color it is, but it shows up pretty clearly in this inverted image. It's really thin too--does that matter?
The line showed up within about 5 minutes. It's a 10miu test strip from the Early Pregnancy Tests website. I've taken lots of these in the same way in the last few days and have never had an evap or a hint of a line even when I took a pic and inverted just to be sure, but I guess it's possible this test is defective and has an evap while the others don't.
Sorry for the rambling! Currently holding SMU & not drinking much so I can maybe test again in a few hours. Thanks for any input!
