Why do I need an Ovulation Calendar ?
The Ovulation Calendar helps you determine your fertile days of the month, so you can either achieve or avoid pregnancy. The calendar is based on the date of your last period, the average Period Length and the Luteal Phase. With this information a chart is generated for each month, including details such as the next period date, the best days to conceive a boy or a girl, your ovulation day and when you should abstain from intercourse to avoid pregnancy.
How to use the Ovulation Calendar
To generate your ovulation calendar you will need to provide three different details:
- Date of your last period.
- Average length of your periods.
- Length of your Luteal Phase.
If you are not sure of the length of either your period or your Luteal Phase, you may use the default values, which represent the average woman.
Although this calendar works best for women with regular periods or menstrual cycles, the average cycle length is also a valid way to predict when the ovulation is happening or should happen.

Becoming pregnant or avoiding pregnancy
The most fertile days for a woman are during ovulation. Having intercourse prior to ovulation or just after it, is a highly recommended form of conceiving a baby.

Gender of your baby (The Shettles Method)
According to Dr. Landrum Shettles and David Rorvik, authors of “How to Choose the Sex of Your Baby”, this method is the most used and most effective.
According to this method Y-chromosomes, for boys, move faster but don't last as long as X-chromosomes, for girls, Dr Shettles says it makes sense to have sex as close as possible to ovulation if what you want is a boy. But if what you want to conceive is a girl you should try to conceive two or more days before you ovulate.
