yes you can get it evey month depending on the body. sometimes its just what the egg is creating to keep it in place it might not be a period sometimes it can be though.
Being late 3 days is nothing. It can even skip a month all naturally. The body is not always on the clock.
No you are not
No - stress or other issues may cause your period to be delayed a day or so but not miss a period altogether. ok if you missed your period one month do not worry just be happy
No it is not bad, as some ladies have a heavy period for one month and then a light one or they may have two heavy periods and then one light one also.
The only thing that happens exactly one month befor a woman's period is her previous period.
A month is a somewhat arbitrary period of time that loosely approximates the period of one lunar cycle.
A women is supposed to have only one period every month, so if she has two in a month which is rare the chances are that she may not have a period the following month.
is not a problem
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 can be possible that a woman can have a period twice in one month. I would talk to a doctor.
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.
You will still have a period every month with one Fallopian tube.
