I'm all confused, my last period was 10th December and I was planning to check everything was working ok by using OPK (recently lost my son and period has been all over the place). I have been testing for 7 days so far and everyday I get a negative on the strip. However, I have been checking my CM as well and its only just started to turn to stretchy egg white. I know this is a good sign, but I don't know what to think - is my body working and the tests are faulty (but surely they can't all be faulty?) HELP!!!!
