as you had taken one unwanted 72 within 24 hours after the intercourse you must have received a withdrawal bleed after 5-7 days. if yes then the date of the withdrawal bleed would form your fresh lmp (last menstrual period) and you should be starting your count for next menses from that date. as the pregnancy tests are negative you are not pregnant from that sexual encounter. hence considering the possible withdrawal bleed your next menses should start only by now. as you have started experiencing mild cramping and vaginal mucoid discharge which are part of pms (premenstrual syndrome) it is indicative that you will start your menses soon. hence please be patient for another one week and you will get your menses. for further information consult an obstetrician and gynaecologist online --> <link>
