Since I still haven't seen AF (it's been about 120 days now) and don't really want to go to chemicals to bring her 'round yet, I was thinking that maybe I should get a fertility monitor. I'd looked at some several months ago, and this one looks really great to me. OvaCue
It monitors electrolite levels in your saliva and there's also a vaginal sensor that will confirm ovulation. The computer stores all the info and charts it for you and you can download the info you a PC to see the chart better. It seems pretty idiot-proof, and I think that's what I need now
There's also a simpler one that just gives you the readings and you have to make the chart yourself that costs a bit less.
At first I thought it was a little extreme for TTC, but, though it hasn't been approved for BC yet, it could be used like FAM for avoiding pregnancy later, so it might not be such a bad investment.
Anyway, I was wondering if anyone here has used it, or knows anyone who has or just has an uneducated opinion
