How to calculate ovulation when the menstrual cycle is 35 days?

Method 1: Observe the next menstruation

If the menstrual cycle is 35 days, the next menstrual period will be on the 14th day of the cycle. During this period, a woman's eggs may mature and be released. Therefore, if you want to determine the ovulation period, you can start observing on the 14th day of the next menstruation and record the 5 days before and 4 days after this day.

Method 2: Measure basal body temperature

Measuring basal body temperature is a common method that can help determine ovulation. Basal body temperature refers to the body temperature measured when you wake up in the morning. Basal body temperature is measured starting on the 14th day of the cycle and recorded in a table. When measuring body temperature every day, plot the body temperature record on a body temperature curve to determine changes in body temperature.

Method Three: Use Calendar

Using a calendar is also a common method to help determine ovulation. Beginning on day 14 of the cycle, record the date and observe changes in body temperature and calendar over the next few days.

Method 4: Combine with other symptoms

In addition to observing your cycle and taking your temperature, you can also combine other symptoms to determine ovulation. For example, if you experience symptoms such as increased sexual desire or breast engorgement during your cycle, you may be ovulating.

All the above methods can help calculate the ovulation period for people with a menstrual cycle of 35 days. However, everyone’s physical condition is different, so these methods are for reference only. If you're not sure how to calculate ovulation, talk to your doctor or professional health care professional.
