I may have only had mine for 6 weeks but am currently very happy with my decision. Decided to get it to prevent a potential pregnancy as the morning after pill was potentially not going to be effective for where I was in my cycle. The insertion was uncomfortable as expected but the nurses were phenomenal, i was given a lidocaine gel and they talked me through every step. Had 24hrs of quite hefty cramps and light bleeding post insertion and it triggered my period early a few days later which was longer and heavier than my usual, but since then things have got back to normal in terms of my cycle length and symptoms I usually experience throughout and my next period came on time. Yes it’s heavier, a bit longer and the cramps are sometimes tough, but with a good regimen of painkillers, hot water bottles and being kinder to myself, i would take that over the risk of pregnancy any day. My partner doesn’t feel the strings when we have sex either. Will update in a few months 😊

Changed from mini-pill after 16 years as I wanted to know my body without hormones and start to understand my cycle better. No issues with the copper IUD. My periods are a bit heavier but they are more predictable and regular. I do have more cramps but they are manageable. Insertion was fine, just uncomfortable. I was surprised how quickly the cramping started after though. I was in quite a bit of pain for an about a week as it settled in.
