No.
It could be influenced by stress, malnutrition, or sickness. Besides pregnancy.
It could be normal if a 15 year old misses her periods by 2 months, particularly if menstruation has only recently begun. Certain changes to lifestyle can bring about missed periods. If this is an ongoing occurrence, it would be wise to seek medical advice.
6 months old.
If the 16yr old was regular and then missed one randomly - she could be pregnant. If she has only just started, it is common for periods to be missed, late, early etc.
Not it is normal, so there is nothing to be worried about (:
Is pregnancy possible? If not, go see a doctor or sexual health clinic.
From when you get your period it can take up to 2 years before you become regular so yes, it can skip several months.
yes its normal , if your period is late you can have brown discharge also it happens after periods and it mean its cleaning out your vagina and old blood looks brown.
No, but I would check with a doctor if it is more than a 2 months, because this could be dangerous or you might caring a child you if your periods do not happen for a while and when you are caring a child you might be have discharges that may look like your normal periods, so get a doctor as soon as possible.
no
It depends... how old are you? And how long ago did you start?
As long as you're not sexually active and have recently started to have periods it is not uncommon for them to be irregular. If you're worried talk to your mum or gp
