Physical anxiety symptoms on period

Simone

So I’ve had an iud for about a year and half now. If u have one, you probably know that your period will be kinda weird for awhile and you might experience different pains/symptoms. For the past half year my biggest issue was that, during my period, I would feel feverish at night. But this period, I’ve started to experience more like the physical symptoms of anxiety. Like my heart beating quickly, restless legs, and having a very difficult time falling asleep. This has been really uncomfortable for me and makes it really hard to relax. Advil/naproxen have not helped. Has anyone experienced this? And does anyone have any advice?
