I'm a 28 year old virgin and not sexually active. my period came 2 weeks late. is this normal? my last period was sept. 1 and then on oct . 18.

It happens sometimes: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… Seeing a doctor is a good idea if symptoms are persistent, recurring, or worrisome.
