FF says I am now 3dpo and I have had all the physical signs of ovulation, but my ic opks have all been negative? Is it possible to ovulate without a positive opk? I've not liked these sticks as they don't really ever get darker than the control line, in fact they are mostly about 75% as dark even on the day before FF says I ovulated. Should I go on my body symptoms or on the tests, and in that case am I not ovulating? I'm going to try clear blue smiley faces next month I think.
