Hi,
I am a seller of Calista ovulation test kits, a tiny microscope that you put a small amount of your saliva on and then look at the ferning pattern that is formed to see whether you are ovulating or not. These are 98% accurate so almost as good as the contraceptive pill. They can be used over and over again so it is a small price to pay and you can check the days you are ovulating.
