As you can see, using an ovulation calculator to predict your most fertile days can be extremely helpful when you want to get pregnant quickly. Since the fertility window is only 5 to 7 days, even a day or two can make a huge difference in whether or not you will conceive this month.

While using an ovulation calculator to determine your most fertile days can be helpful to get pregnant quickly, not everyone has a 28 day cycle. Some women have 26 day cycles, others have 32 day cycles. Using an ovulation calculator and tracking your periods every month will help you determine your most fertile days, even if you have an irregular cycle. Knowing your body will help you find your specific fertilty schedule and ensure that you get pregnant as quickly as possible.

If you want to be more precise and exact about trying to get pregnant, you can purchase an at-home ovulation prediction kit which uses your body temperature to determine whether you are ovulating. It is said that when you are ovulating, your body temperature increases by 0.8 degrees. At-home ovulation kits can give you warning from one to one and a half days in advance as to the best time to get pregnant. This can help you when you are trying to figure out the best times to have sex in order to conceive a baby. At home ovulation kits can also help you to time your cycles so that when you do get pregnant you know approximately when it happened, which can be helpful when it is time to go to your first prenatal exam.
