I *think* I'm 11dpo today and this morning I took a clear blue test (it came with my OPK's) and there was the faintest of faint vertical line to make up the + sign (the horizontal line was dark). I had hubby look at it and we both agreed there was something there with a blue hue but it was so so faint. How are you supposed to know if it's an evap line? It showed right away and I thought it might get darker after a minute or two but it just stayed a faint shadow. I bought some First Response to try tomorrow instead as those are what I used with both my boys.
I hear CB tests give so many false positives or evap lines that look like a positive so I just don't know what to think!
