Things You'll Need:
- Digital thermometer
- Chart
-
Step 1
Purchase a digital thermometer. It is important to use a digital thermometer to track basal temperature because it reads to the 0.10 of a degree. Small fluctuations in these readings can indicate ovulation.
-
Step 2
Create a chart to record your data. You will need two separate columns for your information. One column will indicate the date while the other column is where you will write your basal temperature for the day.
-
Step 3
Take your temperature first thing in the morning. Basal temperature needs to be measured before you get up, talk on the phone, eat, or do anything else.
-
Step 4
Measure your basal temperature at the same time every day. This includes weekends. Set an alarm to help you remember to record your basal temperature at the same time every day to ensure your data is not being compromised.
-
Step 5
Examine your data. Generally, you will know that you have ovulated when your basal temperature is 0.2 degrees higher than it has been for the previous 6 days, and it remains higher for 3 consecutive days.
