now im really confused and ANOYED!! ... looked at the pack that I had just brought from a chemest and it was EXPIRED!!!
OMG, I had the same thing happen with a pack of digital OPKs I bought - they were 14 months out of date when I bought them, but I hadn't thought to check until the second month I used them! So furious!

FWIW, I never get a true positive with the cheap internet strips I buy. The line gets dark, but not as dark as the control. When it gets dark I use a digital test and that gives me a positive. I got the positive at 11pm at night this cycle. My FMU tests are always much fainter.

GL with the timing. I'm not much good at reading the other signs, so can't help you there.
