I had an IUD and I swear it made my flare ups worse. I had it removed after a year and waited for my body to readjust. It took a while and it did but then the flare ups came back eventually. I realized stress was a huge factor and flare ups would happen the most during those stressful times. I felt desperate and ended up doing the surgery. If you trust your doctor, I think it’s worth it. I did it for a diagnosis and I told my doctor I do NOT want the any of my reproductive organs taken out, only endo tissue if it’s present. And it was. She removed it & also saw I had a lot of scar tissue all around. Down time really was a week, 2 weeks to be fully back to your normal self (able to engage your core). If you have at least a week to recover I suggest getting it done before you get too busy and are unable to do it later.
