yes
A woman can get her period twice a month if she has irregular periods.
You will probably have one next month. It sounds like you are having irregular periods. Going on the birth-control pill can often help sort this out and make your periods more regualr.
Yes, they can.
Some medicine can cause the time between periods to increase or decrease. Also having two menstruations in a calendar month is usual; time of periods aren't based on calendar time.
periods could happen twice in one month, but the next month, you might miss
It's not that they are coming twice a month it's just that your period never went off because stress makes your periods irregular meaning that they are changing up and switching when they come on and go off.. So no periods cant come on twice a month.
These may be perfectly normal. You are not a machine and something occur out of order.
The reason why girls get periods twice in a month probably because they have short cycles. I know, because it happens to me. I had my period on Dec 1, 2 & 3 and then I had again on Dec 28,29 & 30 =)
How old are you? If you are still young and just having your first periods, it probably means your body hasn't gotten into a natural cycle yet.
Paid twice a month (24 pay periods a year)
No. The norm is that when you are pregnant you have no period. See a doctor about your hormones, having your period twice in one month is not normal.
No it is the opposite. Not having one is.
