I am asking this question for someone, she is a female 16 year old whos period has been late for two months. her last period was december 23-27,2023. she does not take any medicines, she is not sexually active, but does use nicotine?

Irregular periods are common in adolescence depending on the overall health of the individual. Very athletic women and those with a low BMI are more prone to irregularity. However, this is something that should be brought to the attention of her primary doctor or gynecologist. A thorough history and physical exam could rule out other medical explanations.

Teens and even some adults will occasionally skip a cycle. If she goes past 60 days you may want to contact her doc. Sometimes they benefit from a hormonally triggered cycle if they go too long. The extra time between cycles can lead to a heavy cycle when she does have it.
