Period is when blood comes out of your vagina and you need pads or tampons to stop it from going onto your underwear. It doesn't hurt at all and you don't lose blood from your body.
I'm guessing that you mean menstrual periods so, Your vagina?
Periods are horizontal rows. 7 periods are present in modern periodic table.

Go and see your GP.
You probally just have eregular periods its ok.
While irregular periods could be a symptom of infertility, it does not mean one will definitely not be able to become pregnant. Irregular periods could be symptoms of many other conditions or could be normal in some cases.
You should ask a doctor. I do not know. Sorry.
a hard stomach and twin periods in one month mean you have twins on board.
