Calculate ovulation and intercourse

First, we need to understand a woman’s menstrual cycle. Typically, a woman's menstrual cycle is 28 days, but some may have it longer or shorter. The female menstrual cycle can be divided into three stages: early (14 days to 16 days), middle (28 days to 30 days) and late (30 days to 40 days).

Next, we need to understand how to calculate a woman’s ovulation period. Generally speaking, a woman's ovulation period is between the 14th and 20th day of the menstrual cycle. However, this is only a rough timeline as everyone's cycle is different.

In order to more accurately predict a woman's ovulation period, we can use some methods. First, we can observe a woman's menstrual cycle and calculate her risk period. This means that a woman's menstrual cycle lasts for 28 days, but her dangerous period is between the 14th and 20th day.
