OPK never worked for me. I think a lot of deciding if you have fertile CM or not, depends a lot on knowing your body. After charting my CM i noticed that my fertile CM was not EWCM, but mine was creamy liquidy CM.
i think it mostly just depends on knowing your body. I think that if you think it is fertile CM, then it is, regardless of what an OPK says.
best of luck!
Thanks for the comment, yes i saw the watery and even a little eggwhite CM, now it has gone back to being kind of tacky. does that mean that i can exspect a bfn again or is it to early and i should wait. i wonder how many women went dry after ovulation and still got their BFP that month.
