Females with low weight and body fat tend to have delayed menarche. The time from menarche to regular periods tends to be approximately 14 months, but some young girls start being regular at once. The time between menarche and painful periods (presumably ovulatory cycles) is about 24 months. This varies quite a bit and cannot be counted on as a method of birth control.
