Ovulation Calculator

The human body is a complicated machine and the intricate knowledge of its workings can leave many people seriously baffled. This is especially true when it comes to the understanding of a woman’s reproductive cycles. Ovulation, menstruation and pregnancy are, unfortunately, a huge mystery for the average man and woman. Years of feeling (and being told) that a womans cycle is a dirty, complex and even frightening thing have alienated women and their partners from this important part of life. If you want to start a family and are serious about becoming pregnant, you need to take control of your monthly cycle!

On top of understanding your monthly cycle, cervical discharge and basal body temperature, our ovulation calculator can help to give you a rough idea of when you are at your most fertile in the upcoming months. By entering the date of your last period and the average length of your cycles, the calculator will be able to roughly determine when you are ovulating. Keep in mind however, that many things can affect a woman’s ovulation. Stress, diet and illness can all delay this process and therefore it’s best to rely on knowledge and other indicators as well as the calculator.

In order to successfully conceive, you and your partner have a small window of opportunity every month. Once you’ve ovulated, the egg survives without fertilization for 24 to 48 hours. If you don’t have the faintest idea when you ovulate monthly, chances of being able to grab that two- day window and use it to your advantage are fairly slim. Taking responsibility for your body begins way before pregnancy! You need to learn what you can about your body and when you are fertile in order to boost your probability of becoming parents sooner rather than later.
