Question

Soo, I've had the Mirena IUD for a year now 🙌🏽 and over the past few months, my period has been 7-15 days late, every single time. & when I get it, it's not heavy, at all. Wearing tampons is a waste honestly, because i do nothing but spot, ill even stop spotting, for a day or two & then it'll come back. My periods are now 7 days long, unfortunately 😩 Id say over the past 3-5 months, maybe a few times I'll have a light I mean VERY light flow. Anyone else ever had this happen? Is my period trying to stop all together? Or.. is my body just being weird? Lol.
