So basically, I have very irregular cycles and recently had symptoms of ovulation like slippery cm, twinges etc and my OPK were faint the whole time (close to being positive but not quite). Anyway, since my cm has become more thick but still egg white, more sticky rather than slippery. However over the past 5 days my tests have been getting more and more faint with no positive throughout the whole week. I'm still getting cm but also quite intense cramps so I'm feeling like I missed it!! Has anyone else had this problem with OPK and still ovulated?
