IUD MIRENA CRASH??

Ye
So I'm not on any birth control right now. I had my MIRENA IUD removed August 2, 2016 because I was having really bad cramps- the entire 2 years I had it..and then they found out it had flipped and was making its way into my uterus. I've been other types of birth control for about 5 years now. I did get a period Sept 6-10, but it was very very light and shortest I've ever had. 
 For the past couple weeks I have been feeling nauseous everytime I drink or smoke (hookah/vape).. I'm randomly nauseous too. I am really tired and sleep for like 12 hours and then want to take a nap a few hours later, I haven't been hungry at all for the... which is super unusual because I love food! All I want is water. I keep randomly feeling hot, but I don't have a fever, just elevated temp. My nose is stuffy and I feel like I have allergies, even though I normally don't. 
I'm just wondering if these symptoms are part of the IUD crash? Or if it might just be from my hormones balancing.. or that I'm just crazy.. lol. Has anyone had similar experiences.. I'll take any advice! 😊
