Is there such a thing as a fertility monitor or something telling you how fertile you are?

There are ovulation sticks that you can get from most drug stores. They work a lot like a pregnancy test. They tell you if you are ovulating or not. You can only get pregnant when you are ovultating, meaning fertile. I completely agree. Ovulation kits are 100% accurate. There are 5 testers in the kits so if your period is irregular you may need to purchase 2 packets. The tester will predict your ovulation 24 hours before it happens, so have intercourse as soon as the kit confirms ovulation and 3 days following.
