Ovulation is when your ovary releases a mature egg. Your day of ovulation can vary from cycle-to-cycle and is different from woman-to-woman. An accurate way to identify your personal fertile days is to measure the changes in your fertility hormones. One of your key fertility hormones is Luteinising Hormone (LH), which is the most reliable indicator of ovulation happening within the next 24-48 hours.
