Is this an evaporation line?

[WaitingInAzkaban]

It's very faint, taken 4 days before AF due and disappeared a few minutes later

Was this taken with first morning wee. I can just about see it. Maybe take another one in the morning if you have any left x

I can just about see a line there. I know these ic tests development time is 10mins max, I've never had an evap line with them either.

My test you couldn't even see a line after it dried but I am 8 weeks 4 days pregnant.

Get a first response to confirm it, that's what I did.

Attached a pic of my ic so you can see (or not see) how the lines come up. The single test is the first one I did and the one with the two tests is to show the progression.

I agree with AmyB1986, did the exact same thing. I tested roughly when I expected to be due on (I have very long cycles 34-40 days long) so hard to pinpoint dates exactly, and got a VERY faint line on one of these cheap tests but a definite positive on a first response.
Good luck!
