My friend needs help!

Ashley • Gabriel A. Vargas // 18
My friend said she had her period two weeks ago, and every time she goes to the restroom and wipes there's like pinkish/bright red blood. She doesn't have any discomfort, she hasn't had sex in about a month, she says she feels fine and there's only blood when she wipes/cleans herself. This has been happening for about two weeks, and she can't figure out why!? I keep telling her to go to a doctor, but she says she's fine. Help!
