This ovulation calculator will help predict the day you ovulate as well as calculate your most fertile days to have sex. It will also show you when to expect the first pregnancy signs and symptoms.
If you want to improve your chances of getting pregnant, you need to answer one simple question: "When do I ovulate?" Knowing exactly if and when you ovulate is the single most important information you need to know when trying to get pregnant (in addition to knowing that your partner has a healthy sperm count). You can get pregnant from having sex on your fertile days, which are the 4-5 days before and the day of ovulation. If you know when you ovulate, you can also time sex better.
How To Use The Ovulation Calendar
If you don't know the length of your menstrual cycle or luteal phase, you can leave these at their default values (menstrual cycle: 28 days, luteal phase: 14 days). However, it is recommended that you try to record your own if possible because that will help you to more accurately predict your likely date of ovulation.
For an off-line version of the fertility calendar, check out the ovulation calendar wheel, a unique and affordable tool that predicts the ovulation date, adjustable for short and long cycles.
