30 days menstrual cycle

Is a 30 day period cycle normal?
The length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days.
Regular cycles that are longer or shorter than this, from 23 to 35 days, are normal.
To do this, calculate the number of days between the first day of your last to last period and the first day of your last period.
For example, if in March, your period started on 12th and in April, your period started on 10th, your average cycle length is 30 days, the number of days between the two dates.

When do I ovulate on a 30 day cycle?

Here are some examples: Normal 28 day cycle = ovulation occurs around day 14. 27 day cycle = ovulation occurs around day 13. 30 day cycle = ovulation occurs around day 16._{19 oct. 2023}

Why is my period 30 days long?

Changes to your hormones or ovulation may cause a long period.
You may notice hormonal changes when you first get your period during puberty or in perimenopause.
You may also experience a hormonal imbalance from different health conditions, such as thyroid disorders or polycystic ovary syndrome.

Your menstrual cycle lasts from the first day of your period to the first day of your next period. The average menstrual cycle is about 25-30 days, but it can be as short as 21 days or longer than 35 — it's different from person to person. The number of days in your cycle may also vary from month to month.
