I am 37 years old. My periods have always been very regular, I mean I could set a clock to them. The past 4 months they became very painful and heavy. I started passing large clots, half dollar size and bigger. I have to change my tampon every hour. I started may 15 and have been on my period ever since. Very heavy, painful, with clots. I am starting to feel run down and tired. I do not have insurance, is there something I can do?
