Re: Headache & Cramping TMI
I never got a headache with O, but everyone is different, LOL. Other than that, just from the cervical fluid I would guess it would be your most fertile time. Whether or not you get an egg out of it I don't know...you could be available to O, but not dropping an egg, KWIM? The bding might not be perfect timing to catch an egg, too. Since, in the big scheme of things, your cycle is sort of still coming back to normal it could just be adjusting itself to get you pregnant.
Have you been checking cervix position, using OPKs or anything? If you're not sure exactly what your body is doing, then that's what I would do.
