The lyrics are vague, but the most common interpretation of the song is that it is about the confusion of a girl in love or the mess in a girl's life after she gets pregnant. A girl falls in love with a boy who uses her for sex. After finding out she is pregnant, the boy leaves her behind, leaving her not knowing what to do.
