Having heavy bleeding, periods are always heavy, but like clockwork. Not due til Jan 12. On Wed, had small gush, then second one, then nothing the rest of the night. Nothing all day Thurs til 6 pm. Started gushing big time with clots, haven t stopped. Went through 50 super plus tampons, plus pads in 24 hours. Still not slowing, starting to get concerned. Should I go see dr?
