The ovulation period has a dangerous period, which refers to the period from 14 days before the next period to 10 days before the next menstrual period in a woman's menstrual cycle. For women, this period is very dangerous because if you have sex during this period, you may become pregnant. Therefore, women should be especially careful during this period and take necessary safety measures.

However, safe periods are not always safe. Special circumstances sometimes occur in women's bodies, such as irregular menstrual cycles, making safe periods unsafe. In addition, men may also have errors, leading to sexual failure.

Therefore, women should always be careful and take necessary safety measures. If a woman wants to get pregnant, she should keep trying throughout her menstrual cycle until she successfully gets pregnant. If a woman does not want to become pregnant, she should avoid sexual intercourse as much as possible and take necessary safety measures.

To sum up, women should always be careful and take necessary safety measures. Every period during the menstrual cycle is dangerous, but women should always be careful and take the necessary safety measures.
