I'm guessing maybe this is your younger sister and she's asking you for advice? Are her periods normally very regular? If the first one was really short and/or really light, or this one is, I wouldn't worry about it. But if she has frequent and/or heavy periods, she can get anemic, which wouldn't be a good thing.
