It means you r having trouble and need to tell someone about it
An off and on period is when one month you have it then the next month (s) you don't that's all it means.
It means your weird ....
no, did you get your period?
Time of the month. Time of month. = a period.
Then your done with you cycle for that month
no
Your menstrual cycle basically reset after you took the Plan B. Wait a month from your last period, not from your normal cycle.
If your period is a month late or you miss a period it can simply mean you didn't ovulate that month due to stress or ill health, there are various possible reasons. The odd late or absent period is nothing to worry about, if you miss more than three cycles in a row then see your doctor.
It doesn't mean anything, it just means that your period happened to start on the last day of the month. When your periods start have nothing to do with the calendar date.
Nothing. They vary from month to month.

It could mean you are pregnant, have irregular periods, hormonal imbalance or you have had a light and early period this month for no reason.
