Hi,
Spotting and usually a light blood flow are the first visible signs that your period (
menstrual flow) has started; most young women will notice a spot in their underwear first. A period can last anywhere from 2, 3, or 4 days for the first few months to a year. Other signs can be lower abdominal cramps, bloating, fatigue, irritability, and headaches, etc ~ which are normal...
