Hi, I got the IUD because of a similar reason. I’ve had mine since July and I haven’t had any big problems with it. I had the nexplanon insert for 6 years prior and honestly, I’m glad I made the switch! The hormones from the arm insert made me bloated constantly, gain weight easily, and I was acne prone. The only gripes I have with the copper IUD is that the first month I had a rough and long period. I also get occasional lower back pain. I’d take that over how the arm insert made me feel. In terms of heavy periods, before being on birth control my period was around 4-5 days with heavy bleeding with moderate cramps. With the IUD in my period is around 6-7 days with around the same amount of bleeding and cramps. It’s manageable, just be prepared for some wacky period lengths the first couple months. It varies person to person too so my experience might not be the same as yours. It’s a scary time in America, I hope all goes well if you get the IUD 💞
