How to Use a Basal Thermometer to Get Pregnant

“We’re having a baby!” This is an exciting announcement, isn’t it? Most couples dream about starting a family. Unfortunately, some couples are unable to achieve their dreams due to infertility.

Some couples, due to their busy work schedules, might find it difficult to plan baby making. This is especially true if one partner traveled a lot for work or business, making it hard for the couple to plan intercourse around the woman’s fertile period. 

Women can conceive only around the time of ovulation. A normal ovulation cycle lasts for about 24 hours each cycle. After the release of a mature egg from an ovary, there’s a short time for it to be fertilized by a sperm, which can live for up to five days inside the woman’s body.

Ovulation usually lasts for 12 to 24 hours, and if fertilization doesn’t occur, the egg will die and the uterine lining will shed (in a process known as menstruation).

So, if you wish to increase your chances of conception, it is best to have intercourse a few days before or on the day of ovulation.

How Do You Know Whether You’re Ovulating?

In general, ovulation occurs halfway through your menstrual cycle. A typical menstrual cycle lasts between 21 and 35 days (average of 28 days) starting from the first day of your period until the first day of your next period.

If you are an expert at tracking ovulation using the calendar method, then knowing the ovulation period would be easy, though not reliable.

Otherwise, knowing the signs of ovulation can help you determine if you are ovulating. You can also use other tools such as a fertility monitor, fertility bracelet tracker, or ovulation predictor kit.

I Think I’m Ovulating, Am I?

It is important that you determine when you are most likely going to ovulate to avoid misinterpretation that will result in frustration or worse, depression.

There are several methods to help you find out whether you are ovulating or not. Here are some:

Calendar Method

A calendar is not only a marking pad for holidays, appointments and important occasions. You can use a calendar to find out when next you will likely ovulate.

If your menstrual cycle length ranges between 28 and 32 days, you may ovulate between days 11 and 21, but you will only ovulate on one of these days.

As mentioned earlier, the calendar method is not reliable and only gives you an idea of when you should expect to ovulate.

Body Checking

There are other signs and symptoms that can indicate that you are ovulating. While you may not notice any physical changes, you might experience pain.

If you are experiencing pain in your lower abdomen, this could be your body telling you that it has just released an egg from your ovary.

The pain is similar to menstrual cramps but it is one0-sided and occurs midway through your menstrual cycle (approximately 14 days before your next period).

This pain is referred to as mittelschmerz and doesn’t usually require treatment. Consider the pain as a notification from your ovary that it has released an egg. However, only 20 to 25% of women experience this.

Temperature Check

While temping doesn’t tell you when you are going to ovulate, it may help you understand your body better. In most cases, when you see a shift in basal body temperature, you would have already ovulated.

However, by charting your basal body temperature, you can have an idea of when you’ll probably ovulate and plan intercourse around this period.

Also, your basal body temperature chart can help you know whether you have ovulatory cycles. Your chart may help your doctor understand your cycles if you’re facing difficulties in conceiving.

Why Do You Need a Basal Thermometer?

A basal thermometer is like a common thermometer except that it is more sensitive than an ordinary thermometer. It is designed to monitor the slightest temperature increase of the body.

Your body temperature will increase when ovulate. A basal thermometer is used to determine this increase in basal body temperature, which usually ranges between o.2 to 0.5 degrees.

To have an accurate chart, it is advisable that you measure your basal body temperature at around the same time every day before getting out of bed.

How to Use a Basal Thermometer

You can buy a basal thermometer at your local pharmacy, family planning center, or online. Basal thermometers look like ordinary thermometers but the manufacturer usually indicates “Basal” on the packaging.

There are generally two types of basal thermometers: digital and glass basal thermometers. But there are a couple of things you should know before choosing the best basal thermometer. Read more here.

Digital basal thermometers are mostly used for more accurate readings. Remember, the temperature shown on the digital basal thermometer is in Fahrenheit unless specified by the manufacturer or depending on the device’s technical specifications.

Follow these simple steps to use your basal thermometer:

Condition your body

To get an accurate body temperature, make sure your body is in the right condition – you’re neither stressed nor hyperactive.

The best time to measure your basal temperature is early in the morning just before you get out of bed. Movement can affect your basal body temperature, so you should measure your temperature as soon as you wake up in the morning.

Needless to say, you must have enough sleep (at least three to five hours).

Charting Your Temperature

After getting the result, make sure you record it. Some devices have a recording feature and some smart devices can store up to 60 previous readings.

You can download a basal body temperature chart from Baby Center or use a smart basal thermometer that syncs your data automatically to an app.

Most tracking apps have an automatic chart report of your everyday temperature to help you pinpoint ovulation. You should watchout for a shift in basal body temperature.

Some Points You Must Not Forget

There are several factors that may affect your basal body temperature readings. These include a change in your body temperature due to an illness or a change in the surrounding temperature. If you’re experiencing fever, a cold, body pain, migraine, or cough, you must write that down too on your basal body temperature chart.


Procreation is a lifechagning experience for couples. To successfully conceive, both parties must be physically and emotionally ready. If you’re having a hard time tracking ovulation, it is best you consult your doctor.

Your doctor might want to perform further tests as there are several factors that can affect your fertility.The use of a basal thermometer is highly recommended. It is clinically safe and has proven to be accurate and reliable.
