Period started last friday. By day 6 getting fed up, not usually this long. Day 6, evening, sudden flooding. Day 7, changing towels every hour. Night - horrendous cramps, clots, up every hour to change. Morning (today) - still loads of clots, then the coil itself. Still bleeding very heavily. Feel totally drained, pains, washed out. Have a doctors appt for monday, but should I call for emergency doctor??
