In a woman’s menstrual cycle, her menstrual period occurs on the 11th of every month, and ovulation occurs between 14 and 21 days after her menstrual period. For many women, figuring out when they are ovulating is important because it helps them succeed during sex.

A woman's menstrual cycle usually consists of three parts: menstrual period, and safe period. Among them, menstruation refers to the process of women releasing eggs every month, which usually lasts 4-5 days. The safe period is between 7 days and 13 days after the end of menstruation. This period is a safer time for women and is not easily affected by sperm.

However, the safe period is not absolutely safe. Sperm can survive in a woman's body for 3-5 days, so it is possible to get pregnant even if you have sex during a safe period.

So, how to calculate your ovulation period?

Generally speaking, in a woman's menstrual cycle, the egg is released approximately between 14 and 21 days after her period. Therefore, if you want to get pregnant, you can have sex during this period.

However, please note that everyone's menstrual cycle is different, so calculating your own ovulation may vary. If you are unsure about your cycle, you can consult your doctor or healthcare professional for more accurate advice.

How to make sure you don't get pregnant during sex?

If you want to know when you are ovulating and want to make sure you don't get pregnant, you can have sex during this period. In addition, the following should also be noted:

1. Use condoms: Condoms are one of the most commonly used methods that can effectively protect women from sperm.

2. Avoid overexertion: Women should avoid overexertion, especially in the days after their period.

3. Maintain good health: Women should maintain good health, including a balanced diet and moderate exercise.

4. Avoid the use of emergency contraception: Emergency contraception is not long-term effective, so its use should be avoided as much as possible.

Through the above methods, you can effectively protect yourself from the influence of sperm and avoid pregnancy.
