Yup. choose a time that you can temp every morning where you've been in bed for 3 hours. Asleep is best, but not critical, just in bed covered up for 3 hrs.
Temp at the same time, and chart it. I recommend tcoyf rather than ff as ff's job is to get you pregnant.
Also watch your CM. there are a few major types. Dry, sticky, creamy, wet. There are also matching sensations which is were you just do a few kegels, walk a few steps and interpert how it feels down there. dry, sticky, wet, slippery.
Niamh Dhabolt's FAM Charts - How Does FAM Work?
Niamh's live journal has a crash course, she also has the CM listings. CM trumps temp every time unless you're taking meds that can affect it.
And I find your husbands attitude about "female problems" to be grossly outdated. If mine pulled that I'd probably break his nose. Old fashioned thinking doesn't sit well with me, I find it almost sexist.
