Sometimes your period can be a little late. If you've started playing sports, it's normal if you miss a period or two. I've gone through it myself.
It is not normal to get your period that early. If a 5 year old did start her period then it would be recommended that she see a doctor.
Yes, this is completely normal. Irregular periods are normal within your teens as it takes time for your body to get into a regular pattern of ovulation, and thus into a regular pattern of menstruation.
Yes, It is normal because having period is an important thing for womens.
Yes. Nowadays girls are getting their periods earlier. I am ten years old and just recently got my period last July. I have reserched this question very often and my conclusion is that it is normal for girls to get their period even at the age of as early as 8 years old. So, yes, it is normal for a 10 year old to get her period.
From when you get your period it can take up to 2 years before you become regular so yes, it can skip several months.
depends on the person
It is normal, my daughter also started her period and I was worried that something was wrong. Everyone is different, and I can assure you that it is completely normal. :) x
It's normal to MISS your period if you are 12 because your cycle is not yet stable. (If you had sex, that's different. Talk to your mom if that's the case.)
