Post IUD removal symptoms?

j
I had my IUD removed a little over a month ago. It was taken out on the very last day of my cycle and AF came on time and lasted about 2 days, I experienced spotting for a day, then bleeding again for day. This was fine as I figured my body is trying to adjust. But this month although AF came on time, it only lasted 2 days, my average length has always been 4, maybe 5 some months. And even after it ended I am still experiencing some painful cramping. I can't seem to find anything online about the long term effects of getting an IUD removed so I'd just like to know if any ladies experienced anything similar?
