How many days after menstruation is ovulation?

The calculation method is as follows:

1. Calculate the cycle: Starting from the first day of menstruation, count the days until the clean day.

2. Count the clean days: Starting from the first day of menstruation, count the days until the clean days.

3. Calculate day 14: add 14 days from the clean day.

4. Compare the cycle and the clean day: If the cycle is 30 days, then the clean day is the 18th day, and the 18th day plus 14 days is the ovulation period.

Please note that this method is only a rough estimate, as a woman's cycle can be affected by many factors, such as stress, diet, and medications. So if you're unsure about your cycle, talk to your doctor.

The number of days between menstruation and ovulation is not fixed and can be affected by many factors. For example, if women use certain medications during menstruation, or if their cycles are disrupted, their ovulation may also be affected. Therefore, if you want to know for sure when you are ovulating, talk to your doctor who can give you a more accurate prediction.
