You know what?
I think you're trying too hard. If you only have sex on your "expected" ovulation days, you might be missing your real ovulation days.
We put a big effort into trying for the first month, counting days, "saving up" sex for that magical day 14 or whatever, and nothing. The next month, I was over thinking about it all the time, and not having sex on the wrong days, and then having to have sex on the right days whether we really fancied it or not, and then all the time.... Was that the one? Am I pregnant now?
So we stopped "trying" and had sex when we felt like it. I got pregnant that month, and when I had my first ultrasound, they pinpointed the day I actually concieved as the 17th of febuary. Now I remember having my period just before valentines day, and it finished the day after, so- I concieved just 2 days after my period ended- day 6 of my cycle (it was a very short period) if we'd waited 'till the "right" time- we would have missed it by more than a week!!!!! I wouldn't be sitting here 24 weeks pregnant right now!!!!
I've heard you can spontaniously ovulate during an intense orgasm, and i've also heard that your body will tell you the right time, by making you really fancy having sex- so it seems to me the best way is to jump on your husband whenever the urge takes you, and have a fantastic time of it !!!!!
Enjoy and good luck.
