I had the Mirana IUD placed at the end of Feb. Since then I ve had constant spotting so telling my period has been difficult. Saturday evening I started having horrific stomach pains- felt like I was being stabbed on the left side though not over enough to my ovaries as I sufer from cycsts periodically. The pain would come and go for about 2 hrs and then occasionally on Sunday morning. This morning after using the restroom I noticed white tissue....between the size of a penny and a quarter followed with large clots. Then about an hour later I started bleeding a LOT. I called the dr to get their opinion and am going in for a sonogram to check the placement on Friday but then tonight I passed another large white tisse clot. Is this normal??? What could it be???
