Mirena Help Needed!

I have had the Mirena IUD for about a year now, I’ve had issues with weight gain, anxiety, etc. but out of the blue, I’ve started getting cramps that double me over and give me blurred vision. They are horrible. My primary DR set up an appt for a month from now. Do I need to go sooner? Do I need to go to the ER?

Any help would be greatly appreciated!
