Does hormonal coil (IUS) cause lighter periods?

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.

Wish I'd got the Mirena coil sooner it's been great for me! I have no side effects, my periods have almost stopped except for a little spotting once a month. Insertion for me was a little painful and I had immediate cramps but by the end of the day they had passed (I had an anaesthetic injection which probably helped with the pain). My first period after insertion was heavier and more painful than usual and I had some spotting throughout the month for about 6 months, but now my periods have almost stopped.

Amazing
