Know Your Fertile Window?

Getting pregnant can be a joyous time, however getting pregnant may be difficult especially if your cycle is irregular. Do you know how to figure out your fertile window with an ovulation calculator?

Are you having difficulty getting pregnant? One of the ways to get a handle on this is to use an ovulation calculator to keep you on track. In order to get pregnant, you need to know when you are ovulating. This is known as your fertile window. Using an ovulation calculator will help predict when that time is and hence the most probable time to conceive. These calculators are available online and are free. All you need to do is follow the instructions and the ovulation calculator will tell you when you are most likely to become pregnant.

Your Menstrual Cycle

Your first period or menarche begins your fertile time and will end during menopause. During every monthly cycle you will release generally one egg (ovulation) ten to twelve hours after the hormone Luteinizing Hormone peaks. At this point the uterine wall has regenerated itself from sloughing during you last period. The uterus is now ready to accept an egg that is fertilized. Ideally, if your periods are regular, your most fertile time will be 36 hours after the Luteinizing Hormone peaks. If the egg is not fertilized at this point, the uterine wall will be sloughed along with the egg thus your period begins again. Bear in mind that one day after ovulation is a good time to get pregnant but may continue up to two days later.

Initially, you need to keep track of when you are ovulating to determine a pattern if there is one. This will tell you when it is best for you to conceive. Keep in mind that a man’s sperm can survive inside the womb for anywhere between 24 to 48 hours after you have sex. An ovulation calculator can help you keep track of your best days to conceive once you have put in all the necessary information about your cycle. Essentially an ovulation calculator returns information that is an estimate and also assume a regular cycle. You need to know what kind of cycle you have. For example, do you have a 28 day cycle or a 32 day cycle. Nevertheless, ovulation will probably occur during days 11 to 21 of your cycle. If your cycle is erratic and runs a month and a half and perhaps skips a month, you need to talk with your GYN-OB about your cycle to find out what is wrong and if it can be corrected. It might be that you have more periods than 12 in a year which means you have reduced period times and ovulate earlier than expected. Again, consult with you doctor to see what can be done.

Your ovulation calculator involves measuring your basal body temperature everyday at the same time in the morning. You can do this orally, vaginally or rectally however be consistent with where you take the temperature. Write this down in your calendar. Write down the first and last day of your period to determine the length of your cycle and do this for several cycles. From this you can determine the best time to get pregnant.
