ive had a hormonal iud for about 3 months. I love my iud so much, im terrible at taking birth control so this is so easy. but lately (about a week) i've been getting really bad cramps, not little ones every once and while as usual. Sometimes as bad as the day I got it, I get light headed and out of breath. my period shouldn't start for 8 days and so far has been regular on iud. Is this normal or should I make a gyno appt?

edit- posted this on iud wall and got no response so decided to post here, thanks😊
