Ovulation Monitor

I know ovulation monitors tell you about the time you will ovulate and are used to increase chances of pregnancy.  But I would like to know if you could use them as a supplement to your birth control.  For instance, there are some cases where you could ovulate while taking the pill.  I would plan on using the monitor to see if I am ovulating while I am on the pill (and using condoms) and abstain from sex if I am in fact ovulating.  Does this method sound worth while or are the monitors not accurate enough?

Thanks
