IUD🤮

I’ve had my IUD(Skyla) for about a year and 5 months. I’m regularly sexually active but the past few months I’ve been having the worse cramps. I never had cramps before I got my IUD. I also have periods that last about 7-9 days regular bleeding just a lot of pain. Before my period I begin getting cramps, back pain,and also become constipated. While on my period I just have cramps and the constipation normally goes away. Then when my period ends I have the worst back pain and cramps. I spot after I have sex sometimes but it depends. I’ve been freaking out lately because of all the things I’ve read on the internet, but I’m just sooo scared.
