Hi,
It means Fertility Monitors... They're different from OPKs, as they measure the presence of both estrogen and Luteinizing Hormone (LH) in your urine. Fertility monitors indicate fertility is “high” when estrogen levels are high, and “peak” when they detect a surge of luteinizing hormone (LH). I know Clearblue make them, I don't think you can buy them in Australia stores, but usually available from their website or on ebay.
