I have thyroid, which means irregular periods, and irregular hormone levels. My best guess about my due date for periods has been the discharge I see. Had unprotected sex (no full penetration, just half, for about 3 minutes), when I was having white discharge - which means my periods were about to come. I took the ipill within 14 hours, and today is 10th day after that, and apart from the usual pre-period symptoms (which are apparently the same as that in pregnancy - tender breasts, bloating, mood swings) I haven't gotten my periods yet. Is it imperative for me to get a home pregnancy test? Or should I get it done from a lab? Or should I just wait?
