I have irregular periods i came of on the 16th of july and started on the 18th of june how long is my cycle.

Depends: It could come earlier again, come on time, or even come later. It is not unusual to have irregular periods. Pay attention to any other symptoms such as abdominal pain.

Not certain: A woman's cycle length is most appropriate to talk about when her cycles are regular. When menstrual cycles are not on a somewhat monthly basis the term doesn't apply as well. In general a woman's cycle is dated from the first day of one period to the first day of the next period. If your cycles are very irregular, it likely indicates something abnormal hormonally.
