Calculate menstruation from ovulation period

Women's menstrual cycles usually range from 28 to 30 days, and each cycle contains three complete cycles, namely a week at the beginning of the month, a week in the middle and a week at the end of the month. In these three cycles, around the 21st of each month is the ovulation period, which is the time when the female body produces eggs. An egg only has a lifespan of one day, during which a woman's fertility is at its highest.

So, how to calculate menstruation from ovulation? We can observe the following methods:

1. Observe the menstrual cycle

If a woman's menstrual cycle is 28 days, then starting from the beginning of the month, around the 21st of each month is the ovulation period. If a woman's menstrual cycle is 30 days, then starting from the beginning of the month, around the 14th of each month is the ovulation period.

2. Measure basal body temperature

Measuring basal body temperature can help people predict a woman's ovulation period. Basal body temperature refers to the temperature when people measure their oral or anal body temperature after waking up from sleep. Generally speaking, during a woman's ovulation period, her basal body temperature will increase by 0.3 to 0.5 degrees Celsius.

3. Observe changes in the endometrium

A woman's uterine lining changes during ovulation. During ovulation, a woman’s uterine lining becomes softer and easier to absorb eggs. If a woman's uterine lining thickens, she may become pregnant during this period.

The above three methods can help people predict a woman's menstrual cycle and ovulation period. However, these methods are not 100% accurate because women's menstrual cycle is affected by many factors, such as diet, exercise, stress, etc. Therefore, if you want to more accurately predict a woman’s menstrual cycle and ovulation period, it is recommended to consult a doctor or professional nutritionist.

Estimating menstruation from ovulation is a very important method that can help people predict a woman's menstrual cycle and fertility. Hopefully these tips will help you better understand your body and plan for the right time.
