I am in high school, yet i haven't had my first period yet. should i be worried?

Check it out.: Emily, this could be within the range of normal, or not. It depends on many factors- the age your own mother started having periods, whether you have secondary sex characteristics (pubic hair, breast development) and your age. I suggest finding a health care provider you feel comfortable talking to, possibly a female, and make a medical appointment to discuss your fears and get some answers.

See doctor: Menarche usually occurs between ages 11 & 13 in the US. However for some their period could start as early as age 9 & for others not until 16. Before you have a period, you will have noticed breast development, pubic hair & white to yellowish vaginal discharge. Before the first period a girl may feel bloated, develop cramps in legs or abdomen & feel moody (depressed or anxious). Might be delayed.
