Why do I need an Ovulation Calendar ?
The Ovulation Calendar helps you calculate your fertile days of the month, so you can achieve or avoid pregnancy. The calendar is based on the date of the last period, the average Period Length and the Luteal Phase. Using this information a chart is generated for each month, including details as Next Period Date, when is best to conceive a boy or a girl, your ovulation day or when you should abstain from intercourse to avoid pregnancy.
How to use the Ovulation Calendar
To generate your ovulation calendar you will need to specify three different parameters:
- Date of last period.
- Average length of your periods.
- Length of your Luteal Phase.
If you are not sure of the length of your period or your Luteal Phase, you could leave the default values, which are the average values for almost all women. If you are not sure of the length of your period or your Luteal Phase, you could leave the default values, which are the average values for almost all women.
This calendar works best for women with regular periods or menstrual cycles, but an average of the cycle length is also a valid measure to know when the ovulation is happening or should happen.

Becoming pregnant or avoiding pregnancy
The most fertile days in a woman are when she is ovulating. Having intercourse in the days previous the ovulation or post ovulation is a highly recommended form of conceiving a baby. You could apply this if what you need is to avoid an unwanted pregnancy not having unprotected sex during these days.
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 is the method 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.
