If your daughter hasn't had her first menstrual cycle by 15, or if more than three years have passed since she started developing breasts, she should see a physician.
Some don't get their periods because of hormone imbalances. Girls who are underweight or who have eating disorders may notice a delay in the start of their periods. Girls who are very athletic might not get their periods until they stop exercising or competing so vigorously.
Menarche usually happens 2 to 2 to 2 ½ years after your breasts begin to develop. You can get your period as early as 9 or as late as 15.
Menstruation most often begins between the ages of 11 and 15. If you haven't had a first period by age 15, it's called primary amenorrhea. This is different from infrequent or light menstrual cycles, which are very common in teens, particularly in the first couple of years after menstruation begins.
Amenorrhea has many causes, including hormone problems, eating habits and exercise, or a birth defect. Your teen may need blood tests and a pelvic ultrasound. Treatment may be done with hormones or other medicines, changes in diet or exercise, and calcium supplements.
Most of the time, a girl gets her period about 2 years after her breasts start to develop. Another sign is vaginal discharge fluid (sort of like mucus) that a girl might see or feel on her underwear. This discharge usually begins about 6 months to a year before a girl gets her first period.
Pubic hair – Once her pubic hair starts growing, you can expect her period to develop in one to two years. It may begin soft and thin but it will become courser and thicker towards the end of puberty.

Growing pubic hair: Just after your breasts start to form, you'll probably start growing pubic hair. It will be soft and thin at first, but it'll get coarser over time. Your period usually arrives around one to two years after.
Most girls get their first period between the age of 9 and 16, and puberty normally begins around the age of 8 to 14. Most girls will not start menstruation until they weigh at least 100 pounds. Puberty hormones lead to girls developing breast, hips, pubic hair, and growing in height.
Most people notice spotting as a few drops of blood on their underwear or toilet paper when wiping. In most cases, spotting should not cause concern. Often, hormonal changes due to birth control, pregnancy, or menopause can trigger it.
As I said at the top of this page, manual sex isn't going to change your cycle. And it sounds to me like what you have is a totally normal cycle that's probably pretty regular, and you noticing this change is probably coincidental when it comes to the fingering.
Consider yourself lucky, you don't have to deal with it yet! No worries though, there isn't a set age when girls start their periods, it changes between every different person - some get it earlier than others and some, later. It'll come in due time.
Skipping periods is common during the first 1 or 2 years after they start. It doesn't mean anything serious or cause any harm. A girl can normally go up to 6 months between the first and second periods.
Hormone fluctuations can sometimes affect a person's menstrual cycle and lead to some spotting before their period. This spotting may be more likely to occur when an individual's menstrual cycle is first becoming established. Some periods may be shorter and lighter than others during this stage.
If a fertilised egg implants in the lining of the uterus, the corpus luteum continues to produce progesterone, which maintains the thickened lining of the uterus. If pregnancy does not occur, the corpus luteum dies, progesterone levels drop, the uterus lining sheds and the period begins again.
Pineapple is one of the most cited 'period-inducing' foods. The fruit contains an enzyme called bromelain, which can soften your uterine lining. Your period starts when your uterus begins to shed its lining, and pineapple can help speed this process up and get your period to come sooner.
For some, the first period is light, with a small amount of blood. It may begin gradually, starting with some spotting or brown discharge before becoming red. For others, periods begin suddenly, with bright red blood appearing straight away. In either case, this is normal.
The menstrual cycle does not directly impact weight loss or gain, but there may be some secondary connections. On the list of premenstrual syndrome (PMS) symptoms are changes in appetite and food cravings, and that can affect weight.
Lean body mass in girls diminishes from approximately 80 percent to 75 percent by the end of puberty, while the amount of body fat increases. In comparison, the percentage of lean muscle mass in boys increases from about 80 percent to 90 percent by the time they reach adulthood.
