I'm on cycle day 41, and still waiting for AF to show. I took a clear blue yesterday morning and thought it said negative so I threw it in the trash can. Last night I looked at it further and SWEAR I can see a faint line now. Problem is, I realize that could be the Evap line. So this morning I decided I would take a couple extra tests to be sure. Unfortunately I was up around 7 and had to pee but was out of it so I didn't use first morning urine. I finally woke up around 9:30 and took the tests. One of my Wondfos came back with a faint positive - What the heck!?? Has anyone else ever gotten a false positive back before!?? I thought Wondfos were supposed to be just as reliable!
