Not sure

First off I should say that the issues I’m having started after the first year of use, and I have the mirena IUD. First it started off as my periods being irregular, than several months later I started getting ovarian cyst, I was also in a lot of pain from. It’s now almost a year after seeing the doctor and being told everything is fine and I was getting the cyst, and now it’s been a few months since I got an actual period. The last few weren’t even enough to be considered a period it was way to light and lasted for like a day or two, (knowing I have the IUD in I do know that could be a side effect from it not much of a concern). My main one is that in the past few weeks I’ve started feeling really tired lately, sick to my stomach, feeling agitated and getting irked really easily, also noticed that there are rare times I smoke a little bit or do a Dab ( wax, or as it’s known in a dispensary extract) I will cough and cough and cough until I throw up, which the coughing a little bit after is normal but not to the point I throw up. Really really just hoping it’s a bad reaction to my IUD, 😅. But if anyone has any advice I’d like to hear it.
