Feeling confused

Kristin
I had a d&c at the end of July. I had my first cycle, so we started trying. Had my first period post procedure on sept 14. I used to be like clock work so assumed I would have gotten my period yesterday (being oct 14) nothing yet. I took a test today and it was negative. Of course I probably should have waited but I have this strange heightened sense of smell so I couldn't help myself. Tick tick tick tock....!
