Hi, I am 40 years old and have had fairly heavy periods for years. I started my cycle yesterday, about 4 - 5 days early. It s even heavier than usual. (wearing 2 overnight pads at once and filling them in an hour or so) I am also in alot more pain than normal and very nauseous. I am also having left flank pain but, not sure if it s related. I have a hx of ovarian cysts, uterine fibroids, kidney stones and anemia. Should I go to the ER for this?
