I took the blue line test and it looks like to be a very faint line that showed up within the right time, not after letting it sit. The first response one looks like a very very faint line but it's only if I really look hard could be an EVP line? Am I going crazy. Do evap lines show up right away. It's a CVS test the blue dye one. We have been TTC for a while and this really got me worked up. I don't trust my eyes anymore or my brain I just think I see what I want to see.
