Who made the Fertility Wizard?

I did. Im Sean Gleeson, a designer living in Oklahoma City, Oklahoma.

Why did you make it?

My wife asked me to. She wanted a simple web page that would keep track of her fertility. I made it for her, but anyone who wants to use it is welcome. Its free.

How do I use it?

Just tell the wizard when your most recent (or current) period started. It will tell you what day of your cycle youre on, and whether youre fertile that day.

You can visit the site every day (you may wish to bookmark it) and it will remember you, because it saves a cookie to your computer. So you dont have to input your start date every time, just once a month.

When your period starts again, reset your cycle with the reset button.

How does it know if Im fertile?

The wizard doesnt really do anything you couldnt do with a pencil and a calendar. It counts the days since your menstrual cycle started. If you are on day 8 through day 19 of your cycle, it says youre fertile. If youre on any other day, it says youre infertile.

(Go to the IRH website.)

Is there some way I could keep track of my fertility using the same method, but instead of a free web page, Id buy a necklace with a tiny rubber band that Id have to remember to advance to the next bead every day?

In fact, I believe there is such a necklace on offer through the Institute for Reproductive Health at Georgetown University. I am not affiliated in any way with the IRH; I get no money or compensation from them. But since their necklace was what inspired my wife to ask me to make the Fertility Wizard, Im happy to link to their site. Its a lot more informative than this one, but not as pretty.

Is this method accurate?

Im told this method is 95% accurate. That means, if 100 women use it for a year, engaging in the procreative act only on the infertile days, five lucky ones will still get pregnant. If youre interested, there are far more accurate ways of gauging your fertility than simply counting days, but they involve taking your temperature and analyzing your mucus and whatnot.

Is it for everyone?

Nope. It works for women whose menstrual cycles are between 26 and 32 days long. Most women fit this description, but some dont.

Is it guaranteed in any way?

Absolutely not! While I hope you find this information useful, I assume no responsibilty for any results. Unless youre my wife, in which case Ill assume some responsibility.
