Here's a link that'll give you an idea of what the monitor looks like. It's great. I use it & I just got pregnant after a wierd cycle-- and the only way I know the baby's due date is b/c the monitor told me the exact day I ovulated. http://shopping.yahoo.com/search?p=c...lity%20monitor
I suggest you don't buy it from the link, but research where you can get it cheaper. I'm actually in a study group with Marquette University and I got it free b/c I agreed to send my charts to my doctor every month. So if you can find something like that, it'll cut the cost quite a bit!
Good luck!
