rash between legs.......is it from mirena

I have developed a rash between my legs, and it has done nothing but grow. has anyone had something like this happen. Could it have come from the hormones released from this IUD. I have also had some trouble losing weight. When my son was born I lost a little weight. After my daughter less than a year and half later I had the iud put in and lost no weight. And even still 3 years later none has come off. I have also had headaches, and leg cramps. anyone with some answers please respond. I am thinking of haveing this removed. I have an appointment august 2nd. thanks Tweet
