45 days since my last period .

Its been 45 days since my last period and I'm about a week n a half late . I didnt have my Nov period and still haven't had one this month . Breast tenderness , drained feeling and a little nausea . Honestly I'm scared of dissapointment and maybe since Im TTC maybe its just all going to my head . How long should I wait before its TOO long ?
