He or she will most likely run some blood tests during your cycle to determine whether or not you are ovulating. Any single BBT chart will probably not get you pregnant. As a result, if you have irregular menstrual cycles that vary in length month-to-month, BBT charting will not be as effective.

Women with irregular cycles should always consult with a health care provider to figure out why their cycles are irregular. If you have charted your BBT for several cycles and have not achieved pregnancy or are concerned, talk with your doctor. Bring your BBT charts with you, as they will be helpful in showing ovulation trends and determining if there are any problems.

But it isn't very reliable for preventing pregnancy. Your body temperature dips a bit just before your ovary releases an egg.

Then, 24 hours after the egg's release, your temperature rises and stays up for several days. After ovulation, it rises to You can track your cycle by taking your BBT every morning.

Take your temperature at the same time every day before getting out of bed. Next, record the results on a chart. If you have a somewhat regular cycle, the chart will help you predict when you will ovulate next. The change in your body temperature is very slight, so you need to use a special thermometer. You can use a regular digital thermometer or buy a basal thermometer. A basal thermometer shows you the temperature in tenths of a degree.

Use a digital oral thermometer or one specifically designed to measure basal body temperature. Make sure you get at least three hours of uninterrupted sleep each night to ensure an accurate reading. For the most accurate results, always take your temperature using the same method.

Try to take your temperature at the same time each day, when you first wake up. Track your temperature readings. Record your daily basal body temperature and look for a pattern to emerge. You can do this on a paper chart or an app designed for this purpose.

You're most fertile about two days before your basal body temperature rises, but sperm can live up to five days in your reproductive tract.

If you're hoping to avoid pregnancy, unprotected sex is off-limits from the start of your menstrual period until three to four days after your basal body temperature rises — every month.

Although there are numerous apps available for tracking menstrual cycles, only one is approved by the U.
