Ovulation Calculator

Ovulation Calculator Overview

If your goal is to get pregnant, it can be very helpful to know when you are ovulating and have intercourse based on the information. Ovulation predictor kits can predict when ovulation will occur about 36 hours before it occurs, which has been helped many couples achieve success.

You can measure your ovulation naturally by keeping track of your Basal Body Temperature (BBT) and the amount of cervical mucus you have.

The process of ovulation is the release of one of the eggs from the follicles of the ovaries. The egg then roams down the fallopian tube where it is normally fertilized. The body temperature becomes elevated caused by an increased in the progesterone hormone, which makes for the ideal fertility conditions for the egg.

Progesterone levels will go up about 24 to 48 hours later which will only then raise your body temperature. An egg is viable for about 24 hours and may not be fertilized because the window has passed for fertilization to occur. Keeping track of your basal body temperature each day on a chart can help identify the date you are likely to ovulate and can be used to estimate ovulation patterns in the future. Once you know that date, plan for intercourse two to three days prior to ovulation. This way, the sperm are already in your fallopian tubes, ready and waiting for the release of the egg, which will hopefully make conception occur right away.

This free ovulation calcultor can help you determine when you are fertile, when ovulation occurs, each month to help you get pregnant more easily. Input all of the information regarding your menstrual cycle, including the start of your last period, the length of the period, and the length of the luteal phase. By selecting “View Calendar” you are able to see the personal ovulation calculator.

Use the standard values if you do not know how long your menstrual cycle or luteal phase last. A very good suggestion is to record this information as it will help you determine your next ovulation date.

Choose “girl” or “boy” in the gender field if you have a preference as far as gender.

It is important to know that the ovulation calendar performs best for those with a regular menstrual cycle. We are continuing to increase the number of NFP fertility indicators in the program like cervical mucus, basal body temperature charting, and cervical position observation in an effort to help women with menstrual cycles that are irregular.

Method to obtain your Basal Body Temperature: A special ultrasensitive BBT thermometer to do this. This thermometer is fairly cheap, around $10, and measures in one-tenth increments. Your Basal Body Temperature will be measured by oral or vaginal methods, with the oral method being the more accurate one. Whatever method you select, stay with that during your cycle. The BBT thermometer has to be placed in the same spot of your mouth or vagina each day.

A BBT temperature is known as your temperature with your body at rest, so when you first get up in the morning. You should take the BBT immediately when you wake up after sleeping for a minimum of three hours, and before doing any sort of activity, especially things like showering or eating breakfast.

Body temperatures can vary up to one tenth of a degree for every half hour that you are off in taking it at the normal time. If you didn’t take your temperature at the regular time, regulate it using this regulation.

Body temperature is also altered by fevers, lack of sleep, alcohol, or even changes such as jet lag or a different schedules.

Ovulation Calculator How to Chart Your BBT Temperature

The ideal time to begin charting your BBT temperature is on day 1 of your menstrual cycle. Beginning when you are in the middle of the cycle can lead to confusing and inaccurate results. Begin graphing your BBT temperature in a notebook. Every day, record your body temperature, making a note of the time and whether there is any reason to expect a significant change in temperature (if necessary).

Determining Ovulation

Your body temperature will vary two times throughout the menstrual cycle normally, but it will vary three times with conception. The normal temperature during the first two weeks of the cycle is between 96.5 and 97.5 degrees, and 97.6 to 98.6 after ovulation. The change of temperature before and after ovulation is due to hormone shifts. Post-ovulation temperatures will stay high for twelve days or more until your cycle is over and the next period begins. If impregnation happens temperatures will remain raised throughout all of the pregnancy.

Charting the deviations allows you to determine your ovulation period. Optimally, a temperature rise of about 0.4 degrees from your previously recorded temperatures is a good indication that ovulation is possible over the next 48 hours.

You should see a pattern of ovulation begin to develop after several charts are done, which will allow you to determine the best time for intercourse.

Signs That Could Indicate Potential Pregnancy

You should take a pregnancy test if you have had an elevated Basal Body Temperature consistently for eighteen days post ovulation.

Limitations of BBT Ovulation Calculator

Making a chart of Basal Body Temperature will only indicate that ovulation already happened. Because an egg only lives for 24 hours, when you find out you have ovulated the egg is no longer available because your temperature goes up 2 days after ovulation. The importance of BBT is it can help estimate certain patterns and if your cycle is regular could assist you in figuring out your next ovulations. An Ovulation Predictor Kit is a better way to determine when ovulation will occur.

You should also take notice of other body signs, including cervical fluid and position, when you are making a chart of your Basal Body Temperature. To find the precise time period when you are most fertile, combine and calculate those three factors together. I hope the Ovulation Calculator has been of help.
