I'm almost 28 years old, have had periods for the last decade and a half. They have always been regular and heavy to the point that if I didn't take iron supplements 5x a week and tranexamic acid during my periods, I'd have anemia. So I got Kyleena in December 2024. Insertion was fine, some cramping but nothing too serious. I had cramping on and off during the times my periods were supposed to come and some spotting/bleeding, but it was usually what I saw towards the beginning of my cycle. I had one reduced-level period in mid-August. I have had to go from 36D to 36DD to 36DDD/38DD bras over the span of a few months. At first I thought it was just weight gain (went from 170 to 195lb), but I have been almost 200lb before and my breast size increased this much this quickly. Even after losing 10 pounds my breast size has shown little to no decrease. I hate it. I also suspect that the IUD influenced my sciatica in my lumbar spine, which began in February 2025 and has taken several weeks of PT and a round of oral steroids to resolve. I am still not up to 100% all these months later. Overall a 2/5. The decreased period length, flow, and frequency is almost not enough to justify having this torture device in. If I get pregnant w/this in, I'll be so angry.

Getting it in hurt briefly, but tolerable. The first period after getting it was early and super intense, and I continued having spotting most days for the first three months or so, but bleeding dwindled over time and by a year later I was barely getting periods at all, which was great.
