This free ovulation calculator and fertility calendar acts as a ovulation predictor by calculating the day you ovulate, your fertile days for sexual intercourse, and helps improve your fertility. It will also show you when to expect the first pregnancy signs and symptoms. Knowing exactly if and when you ovulate is the single most important fertility information you need to know (in addition to knowing that he has a healthy sperm count). You can get pregnant from having sex on your fertile days: the 4-5 days before and the day of ovulation. You can time sex better if you know when you ovulate.
How to use our free ovulation calendar
If you don't know the length of your menstrual cycle or your luteal phase, you can leave these at their default values (menstrual cycle: 28 days, luteal phase: 14 days). However, it is recommended that you record these as they will help you to more accurately predict your likely ovulatory date.
Want a boy or a girl? Did you know that eating a certain diet PLUS timing sex can improve gender selection? Read more about the "Girl Diet" HERE. Make sure you know whether your menstrual cycles are regular HERE. Then choose "boy" or "girl" and follow the instructions. Our calendar follows exactly the Shettles Methods of Choosing the Sex of the Baby.
Finally, if you're already pregnant, try our Pregnancy Calculator to find out when the baby is due. In addition to this calendar, there are a variety of ways to help predict ovulation such as with LH ovulation tests (OPKs) or Fertility Monitors. Or, for an off-line version of the fertility calendar, many women have benefitted from the Ovulation Calendar Wheel, a unique and affordable tool that predicts the ovulation date and is adjustable for short or long cycles.
