After your Mirena IUD was inserted, how long did it take for everything to feel basically normal again?

From what I’ve read, I’m lucky to have had an easy insertion with very little cramping afterwards, and no cramping or other pain since then. But I’ve been bleeding moderately (like an average-to-light day of a period) EVERY DAY of the six weeks since the insertion. My gyn says it’s okay, my IUD is okay, everyone responds differently, and it might take months to normalize. So what was your experience in terms of how long it took for your post-IUD symptoms to go away?
