Hi,
Some women track the fertility by taking temps, using opk's, checking cm etc.
I have been on 6 rounds of Clomid and will be doing a few more rounds from January 2012 and will be monitored throughout so I don't worry about charting.
My FS told me that by having sex every other day it gives you maximum chances as there will always be fresh, healthy sperm waiting and charting causes women to stress a lot more than if they weren't charting.
If it gets to a year and you still have no luck then I would advise visiting your doctor and they can run hormone tests to see if there is anything wrong and check your fellas swimmers too. More often than not, you will will also be given the option of a fertility clinic referral.
Good luck. x
