No Blue Lines - Blank Test, 2 Days in a row - HELP!
Using the 7-pack OPK, and have gotten a ZERO read two days in a row - as in NO blue lines whatsoever. I just bought the kit, and the expiration date is 3/17 - so that's fine. Do I return and try another kit? It's incredibly frustrating to have possibly missed a window because of a faulty kit. :-(
