How to calculate ovulation when menstruation is long?

Method 1: Observe symptoms before menstruation

Before menstruation begins, women may experience a series of symptoms, such as headache, breast swelling, fatigue, nausea, etc. These symptoms usually appear in the days before menstruation, so women can tell when they are ovulating by observing these symptoms. For example, if a woman experiences headaches and breast swelling before her period, she may be ovulating tomorrow or the day after tomorrow.

Method 2: Measure basal body temperature

Measuring basal body temperature is another common method that can help women better determine when they are ovulating. Women can measure their body temperature when they wake up every morning and record changes in body temperature. Generally speaking, women begin to measure basal body temperature on the 14th day of the menstrual cycle, and the body temperature will increase in the next few days until it reaches a peak of about 37 degrees. If a woman's temperature continues to rise during this period, she may be ovulating tomorrow or the day after tomorrow.

Method 3: Use ovulation test strips

For women with long periods, it may be helpful to use ovulation test strips. An ovulation test strip is a test tool that tests whether a woman is able to release an egg. It can usually be used starting on the 12th day of the menstrual cycle. If a woman shows two obvious lines during the test, she may be ovulating tomorrow or the day after tomorrow.

No matter which method you use, women with long periods need to be patient because it takes several days for the egg to be fertilized after it is released. In addition, women can also predict their ovulation period by observing symptoms and measuring basal body temperature, but this is only a reference and cannot predict a woman's ovulation period completely accurately. If a woman is unsure about her ovulation period, it is recommended to consult a doctor or medical professional.
