from being so anxious about your period being late delays it a bit more. since your ept came out negative you can relax for a week or so. being placed on the antibiotics have an affect on menses. if you haven't gotten it by today's date then by all means go to a gynocologist - that doctor will take tests with an exam to determine what's going on.
