Yes! they can be irregular up until her twentys, many women have irregular periods to start with and it is perfectly normal.
Yes, it is perfectly normal to have irregular periods at first. Most girls worry about it at first, but there is no need.
OK... wow! i would take her into a doc. this might not be normal.
No, you are not pregnant. Sometimes Periods are just a little irregular, it is normal though.
No irregullarity is normal
your period will never be the same everytime
No. But its not all that unusual either ... at least 10 % of women have irregular periods. You can get a work-up at your gynecologist, but some just don't have a cause.
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.
It can take months for your periods get back to normal, especially if you are breast feeding you can miss periods or have long times between them. You can still get pregnant while breast feeding and having irregular periods though so you should still use contraception.
Yes, it is normal because you probably just started your period. You are usually irregular for your first 2-3 years then your periods will becoem normal. This may also have to do with if you shave your pubic hair cause blood will only come out if you have tons of hair "down there."
Any girl/woman can have irregular periods. It is not always a bad thing but I would keep an eye on it and if it happens TOO irregular talk to your doctor about it.
Sorry but this question isn't very clear. . . If your period was due on the 1st then that is normal yes. If you are bleeding again on the 12th and you had your period on the 1st then this is normal if you have just started your periods within the last year. If you are on birth control, have irregular periods, are stress or worried about something then this will cause two periods in one month but see your doctor for a check up.
don't worry your periods are just irregular. its completely normal.
