Mirena IUD - spotting/light bleeding

Victoria

I’m sure this is normal but does this stop at some point?? I got the Mirena IUD in August and besides the cramping, bleeding. and back aches for a few days, mild cramping and light bleeding on and off for a few weeks its been fine. But it’s November and I feel like I’m constantly wearing a pad, I’m always spotting or gave a light bleeding that’s like brown? Like it’s old blood or something. It’s so annoying and I can’t wait for this to all settle down. But how long do I have to keep going through with this until it stops?
