Does hormonal coil (IUS) cause spotting?

I’m 44 with recently diagnosed PCOS and endometriosis which is why my specialist told me to try the Mirena to lighten the lining of my uterus and help with my awful periods. I had to go off of the pill at 40 and suffered for 2 years while debating what to do. I got the mirena in at 42 and have had it 2.5 years now. I do get pelvic pain and cramping twice a month for a few days randomly and feel like I can tell which ovary is active but it is still better than dealing with the bleeding and irregular periods I had previously. My periods are non existant apart from spotting for a few days but not enough to even merit wearing a liner! Sex drive is definitely lower and dryness comes and goes as well but breasts have grown which I’m not upset about! I’m leaving it for another 2 years then will decide if I should opt for a hysterectomy.

the coil was much better than the pill for me, especially in terms of my mental health.

I never leave reviews but felt like I needed to because I was terrified of getting this, I’ve always struggled with hormonal acne, thrush and am incredibly susceptible to drastic mood changes due to birth control. This was my last hope as the pill never agreed with me and I didn’t want the heavy bleeding from the copper coil. The insertion was really not even bad it did hurt a bit but was over so fast, I even went for a walk with my friend that evening and was absolutely fine! I had some cramps and bleeding for a few days after but nothing major and since I have had no side effects except a late and very light period that’s it! So please don’t be as terrified was after hearing so many horror stories, I was completely fine :)
