Asking for a friend who is trying for her first baby: what is the best way to measure ovulation?

To add on to what the ladies have suggested, you can also keep a lookout for changes in your discharge. During the time of ovulation, the vagina’s mucus is usually clear, slick and slippery with the consistency similar to that of an egg white. Another way is to keep a record of your basal body temperature every day before you get out of bed. You will need to purchase a special basal body temperature thermometer. Once ovulation has occurred, you should notice that your BBT would rise by about half a degree Celsius. However, this method is only useful in helping you note down your ovulation cycle because the change in temperature takes place only after ovulation. Therefore, you would have missed the most fertile period if you wait till raise in BBT.
