How do you calculate ovulation when you have your period every two months?

1. Basal body temperature method: Measuring basal body temperature can help determine the ovulation period. At the beginning of the cycle, take your body temperature and record daily temperature changes. During ovulation, body temperature usually rises by 0.3-0.5 degrees Celsius.

2. Observe symptoms: During ovulation, women may feel some symptoms, such as increased sexual desire, breast swelling, headache, fatigue, etc. These symptoms may not be experienced by everyone, but they can help determine ovulation.

3. Measure blood pressure: Measuring blood pressure can help determine ovulation. At the beginning of the cycle, blood pressure is measured and daily data recorded. During ovulation, blood pressure may increase, but it may also decrease.

4. Use a calendar: Using a calendar can help determine when you are ovulating. At the beginning of the period, mark the time on the calendar as undated and then insert the number of days between possible dates. Every day between possible dates is a possible ovulation period.

While these methods can help determine ovulation, they may not work for everyone. For women who menstruate every two months, it is best to consult a doctor or other professional to ensure the safety and effectiveness of the calculation methods and recommendations.
