Menstruation

It depends on what you mean by 'safe' - if you mean when it is safe to have sex without becoming pregnant, then any day when you use birth control! A woman is only fertile for a maximum of 9 days, around 48 hours when she ovulates and up to a week beforehand when there is fertile quality cervical mucus present which could see sperm survive up to a week. You can guess when these days will be based on your past cycles, this is known as Rhythm Method, but this is totally unreliable because your cycl;es can change and even getting it wrong by a single day can be the difference between being 'safe' and sex resulting in pregnancy. The only way to accurately tell when you are fertile or not is if you use Fertility Awareness Method to monitor your cycles on a day-to-day basis.

The average age of menarche (first period) is 13 years old, but anything between 8-18 years old is still considered normal - typically menarche starts within four years of startig puberty so if you have symptoms such as breast growth, discharge, bodily hair, pubic hair, etc. then you are right on track and your first periods will start faily soon.
