No, months have no effect on your menstrual cycles.
When you get your period depends on your menstrual cycle. If you have a 28 day menstrual cycle you will likely get your period once per month, where as if you have a 20 day cycle it is possible to have two periods in one month - e.g. you could get your epriod on the 1st of the month, then again on the 20th of the month.
When you are on your period
Your menstrual cycle basically reset after you took the Plan B. Wait a month from your last period, not from your normal cycle.
A month is a somewhat arbitrary period of time that loosely approximates the period of one lunar cycle.
For women who think that their period should come on the same calendar day of every month, a short month like February or a slew of long months like Dec/Jan can be confusing. If you aren't at risk of pregnancy, you are surely "OK." If you don't get a period over the next three months, contact your health care provider.
Then your done with you cycle for that month
For most girls it will start about a month later but it may start a bit later or earlier then that. When you are starting your periods your cycle may vary so it can be at different times. When you reach adulthood you will most probably settle into a regular pattern. If your period is more then 2 months late then you will have to go to your doctor straight away. In case you were wondering what a cycle is: A girl's cycle is counted from the first day of bleeding in one month to the first day of bleeding in the next month. So if a girl gets her period on January 8th and then again on February 2nd her cycle lasted 25 days. (from January 8th through february 1st)
Periods can be irregular, especially in younger women. Hormones control your cycle.
Yes, your period isn't determined by the calendar date but is determined by your menstrual cycle - if your menstrual cycle was only 21 days long then you could menstruate on the first of the month, then again on the twentyfirst of the month.
