Ovulation occurs within a few days after your period ends. Generally speaking, the ovulation period occurs within a week after the end of menstruation, which is also called the "danger period". If you want to get pregnant, you should take steps during this week.

So, what are the dangerous days after menstruation? Generally speaking, the week after the end of menstruation is a dangerous period, but the specific date will vary depending on individual differences. Generally speaking, the first day after the end of menstruation is the safe period, while the second to fifth days are the dangerous period.

However, the safety period is not absolutely safe. Some people may experience symptoms a few days after their period ends, such as headache, breast discomfort, fatigue, etc. If you have these symptoms, it could mean you're at risk.
