So I went to the ER Friday night said I have kidney stones and a cyst on my ovaries. Since late Saturday night my period came (last period was 21st of January now Feb 2) this is like no other I blew through a box of pads in a day and a half. I went through 4 pants & 4 undies in less than a day my cramps are horrible I'm crying out in pain what should I do go to ER again?

Yes. If for no other reason than to monitor your blood loss.
