Suggest Treatment For Uterine Contractions And Heavy Period

I am 35, I have pcos, I spot almost everyday, not enough to wear a tampon. I went a week or two without any spotting. Now I am having a period that is so bad. I am using super plus tampons and pads. I have to change every hour or so. The blood clots are large over one inch and there are tons of them. I can barely walk, it feels like Im having labor contractions. Should I go to the emergency room
