BC Advice! 😢

Hey there so here's my story:
I started the pill last September and I was on it until December. During this time I had my first sexual encounter and we were safe and everything seemed fine, but then I started dwindling health wise. The thing is the pill triggered a thyroid condition that was very extreme and caused me to lose my hair, gain weight, get panicked and sleepless and get very sick. My doctor took me off it immediately and said any hormonal form of borth control would have the same effect.
I also learned I cannot take plan b for the same reason because after I was taken off the pill we used condoms and we broke one. The plan b had the worst effect on me. It set me back months, but I am not ready to get pregnant.
The only option of birth control that may work for me is the copper IUD. I have an appointment set up for this Friday but I'm so damn nervous. 😭😭😭
Guys I just started to lose the weight, get healthy and feel like myself again. It was the hormones that messed up my body but I'm so tentative to get the copper IUD just because I'm scared something else will happen. I can't keep onlybusing condoms because there is no way for me to use plan b so I feel like the Paraguard is the best option but I really need some words of encouragement or experience with this form of Birh Control. 
Honestly anything you have to say would be so helpful! This community is so beautiful and I am so glad I can ask this to people like me.
