Things You'll Need:
- Notebook or journal
- Pen or pencil
- Digital thermometer

Step 1
On day one of your period, begin a daily routine of checking your temperature while still in bed, after at least three hours of continuous rest. It is crucial that this temperature be taken while resting as physical exertion can increase your temperature. It is also important that you do not eat or drink anything prior to taking your temperature.
-
Step 2
Record your temperature, including the tenths of a degree. An increase of .04 to .06 degrees can indicate ovulation has taken place. This information, collected over time, will help you recognize all the signs that take place right before ovulation.
-
Step 3
Part of your daily routine will also include checking your cervical mucus. Over the course of your menstrual cycle, the amount and color of your cervical mucus will change. It is important to note these changes. Check your mucus level with some toilet paper or clean fingers.When you are not fertile, there will be a lack of mucus. As you get closer to ovulation, cervical mucus will appear and will become increasingly more like a raw egg white. There will also be more mucus. This is when ovulation occurs. Afterwards, the texture of the mucus will change and it will eventually dry up as the cycle begins again.

Step 4
The last part of your daily routine will consist of recording a calendar-type log of your menstrual cycle. The first day of your period is day one for your calendar. The last day of your calendar is the day before your next period begins.
-
Step 5
Once you have recorded you menstrual cycle calendar for several months, you can use the cycle that was shortest in length for your calculation. Subtract the number 18 from the total number of days in that cycle. For example, if that cycle totaled 29 days, subtract 18 from it. The result is 11. Now take your result (11 in this example) and count that many days forward from your current day one. This may be the day you will ovulate.
-
Step 6
After several months of recording your temperature, your cervical mucus stats, and your cycle calendar, pinpointing the day in your cycle you are most likely to be ovulating will be easy. It is not guaranteed to be correct every time, but it is a highly accurate way to determine your ovulation cycle.
