The first period's symptoms include breast development, pubic hair growth and discharge. These symptoms occur during puberty as an indication of sexual maturity in women, says Always.
Development of breast buds starts around two years before the onset of ovulation. Breast development begins as buds and can take between three and four months before they attain the mature size. Pubic hair growth starts soon after the onset of the breast development and starts as soft and thin fibers before getting increasingly coarser. The first period's onset happens around two years after the onset of the pubic hair growth. Discharge occurs a few months before the first period, and may have a characteristic white or yellowish appearance, notes Always.
