I'm 18yo, virgin, have usually regular period. i missed my period this month. however, during my expected days acne occurs. what happen with me ?

Don't worry: Irregular or missed periods can happen and is nothing to worry about if you are otherwise feeling fine. Sometimes stress, change in diet, exercise, hormones or illness can result in a missed period. If you are otherwise healthy with healthy lifestyle don't worry. If it happens again or is associated with illness or bad habits see your doctor.

Virgin: It is not unusual to miss a period at your age but the hormones in your system may have aggrevated your acne.
