it's too early to be anxious!!! you may be offered an interview anytime between now and may--or never! not everyone is offered an interview the first time their app is looked at, so there is no pre-set formula regarding how long it takes. besides, how often the admissions committee meets varies from school to school. since the interviewing season is just beginning, you'll never make it until next spring if you start to worry now. just kick back and be happy that your secondaries are done.
