First time getting IUD

Victoria

My first time taking birth control was this year and I was on the patch. I didn’t really like it do I talked to my OB about a different birth control and he recommended an IUD from Mirena. With the patch I was spotting for a good 2 or 3 weeks then my period would come plus I would get random cramps that were unbearable. Ugh, I hated the patch so much but now I’ve been reading about Mirena and all the problems people have with it. I have an appointment in 2 weeks to get it inserted. Are there any advantages or disadvantages that people have had with it. I also got a lot of mood swings with the patch so I hope I don’t get the same mood swings on Mirena. I just want to know from people’s own experiences.
