If you are attempting to get pregnant you should know that there is a specific window of time to get pregnant for every woman. By paying attention to what your body is telling you, you will be able to calculate when you can become pregnant.
Some of the things that you can do to help understand when you are most fertile is to watch for the changes in your body temperature, changes in your vaginal mucus, or you can even purchase an ovulation predictor kit that reads the hormone levels in your urine.
Knowing the exact window of time when you are able to become pregnant can help you to know when you should have intercourse so that you can conceive. Sperm is only able to fertilize your egg for three days, however, after ovulation an egg is only has the capacity to be fertilized for 24 hours before your body sheds it. Knowledge is power and knowing when you ovulate will greatly improve the odds of your getting pregnant.
When will you be most fertile?
About 11 to 18 days before your next period is when you are the most fertile. To make an ovulation calendar you can use the calendar on your computer, cell phone, or the paper one on your desk. Circle the day that your period begins, you should do this for 6 to 12 months to get an accurate picture of the duration of your menstrual cycle. You will need to count the number of days from the first day of bleeding until the day before your next period. Don't guess or assume, you need to be accurate about the length of your cycle, if you are a day or two off that could be the difference between getting pregnant and not.
The next thing that you will need to do is to count the number of days in the shortest cycle of the time that you recorded and subtract 18. Whatever number that you come up with, take it, and start counting that number of days beginning with the first day of your next period and that should be the first day that you are fertile.
So now you have the first day, let's figure out the last day. Subtract 11 from the number days of your longest cycle. On the first day of your next period, take the difference and count that many days forward and mark your calendar because that will be the last day that you will probably be fertile.
Don't rely on your ovulation calendar for birth control.
One thing that should be noted is that if you are on any form of birth control that you need to stop taking it before you can start an ovulation calendar. If you want to get pregnant then the upside is that you can have all the sex that you want during your fertile time frame. Often and frequent is the best way to achieve your goal of pregnancy.
If you don't want to get pregnant then you will either have to abstain from intercourse during your fertile time window or use a condom or diaphragm, but it should be noted that an ovulation calendar is not a reliable form of birth control.
