Confusing OPKs

Well the opk was - tonight no line what so ever and I have had no EWCM so I don't know what to think but then again I ddin't have as much creamy or watery as I normally have so thinking that the clomid is drying me up slightly thankfully we have preseed.
I guess tomorrow will tell if the cm dries up or not and what my temp dose although my temp this cycle has me scratching my head
Its back to work tomorrow I am not looking forward to it. My knee has gotten lots of rest this weekend and it is only mildly bothering me still swollen like a water melon but not as sore tormorrow will tell me how much it hates standing in one spot at work
