Constant spotting?

Robin • Im 19, my boyfriend is 23. He is amazing, ridiculous, gross, incredibly sexy, and the love of my life. 😻
I have had my Skyla for 5 months now and I still am spotting. Its an on/off thing every day or so, its an odorless discharge that is rusty toned but thicker in texture than my actual period which I havent had since before my IUD was inserted. Just wondering if anyone else has a similar problem and how long I should wait for it to go away. My doctor said that everything looks good down there and that its completely normal with nothing to worry about.
