How to calculate ovulation when menstruation lasts 26 days?

First, we need to understand the menstrual cycle. The menstrual cycle is the number of days from the first day of menstruation to the first day of the next menstrual period. For women who menstruate for 26 days, the cycle is approximately 28 days.

Then, we need to understand that during a woman’s menstrual cycle, her ovaries release a mature egg. Generally speaking, women begin to release eggs on the 14th day of their menstrual cycle, but this depends on the woman's menstrual cycle and the cycle of her ovaries.

So, how to calculate a woman’s ovulation period? We can determine the ovulation period by measuring body temperature starting from the 14th day of menstruation.

First, we need to collect body temperature data. Generally speaking, a woman's temperature will be measured and recorded every morning when she wakes up.

We can then plot the body temperature data into a graph. On the day when body temperature is highest, which is when a woman is ovulating, a woman's body temperature will drop.

Determining ovulation by measuring body temperature can help women better control their menstrual cycle and take appropriate measures to promote fertility.

In general, calculating a woman's ovulation period requires understanding the woman's menstrual cycle and ovarian cycle, and measuring her body temperature to determine the ovulation period. Through these methods, women can better control their menstrual cycles and promote fertility.
