I haven’t had a period in almost a year, last december i came off the pill completely and after that no signs of period, about 3 weeks ago they put me on provera to start a period, it started friday and today is the heaviest it’s been, im having an insane amount of blood clots, and having to double up my pad bc if i don’t it has to be changed every 30 mins or so. the blood clots range from size of a grape to as small as the tip of a bald point pen, should i be worried?
