TLDR: -If you struggle with PMS already, please ask your doctor about the effects progesterone only birth control can have. I wish I had known that it can make it worse. -Expect new kinds of cramps. For me it was lightning rectum pain

I’ve only been on it for going on 3 weeks now. The first week was cramping and low back pain. Week 2 was nausea and hunger pains. I’m starting week 3 now and I’m working with my hunger, tiredness, and possibly some mood swings. So far I really like it. I don’t feel it, it doesn’t hurt or nothing.

I got the Kyleena prescribed off-label to me after suffering from ridiculously heavy periods in my teens. I used to bleed 200mls+ on some periods and even Tranexamic acid didn’t help. This IUD has been an absolute life-saver and my periods are so much lighter. I will admit I have experienced some side effects - I used to have clear skin 95% of the time, however since the IUD I permanently have 1 or 2 pimples around my jawline which can be quite annoying. My periods are often very long now (7-11 days) despite being light which also gets frustrating. Those are the two main side effects I’ve experienced, but overall it’s been a positive experience.

I got the Kyleena prescribed off-label for my heavy menstrual bleeding. I used to bleed sometimes over 200ml per period, even Tranexamic acid didn’t help. This IUD has been a life saver - my periods are so much lighter. Overall it’s been a positive experience. I won’t pretend it doesn’t have other side effects though. My periods are now way longer than they used to be (7-11 days) although not heavy at all. I also had clear skin 95% of the time prior to the IUD but now I permanently have one or two pimples around my jawline which can be pretty annoying.

I’m pretty pleased for the most part. It’s my 2nd IUD, first hormonal one. My periods are pretty much gone and I love that. They were pretty bad before. The downside is that my scalp sweats PROFUSELY with very little physical exertion and my face is super oily. So much so that I have several pimples along and into my hairline. I’m very upset about that. I’m on month 7 and the pimples just started, but the sweating and oil started almost right away.

Didn't use it long enough to really form an opinion yet, but the reason I got it in the first place was because of very heavy periods and cramps. It has helped with that.

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.

I have been on kyleena almost 5 years, January 2025 it will be 5 and little to no problems. But I didn't know there was a mucus discharge, had thought I always had a yeast infection. Almost time to get a new one and I've started spotting again.

This caused pain/vomiting/inability to sleep for 3 months after insertion. I was promised it would improve, and told to just keep giving it time. Severe menstrual cramps continued the whole 2 years that I had this. Doctors promised many times over the 2 years that my symptoms were normal and/or not due to the IUD(both incorrect). Around the 9 month mark I began to develop progesterone hypersensitivity autoimmune disease. This continued to progress until I removed it. This new condition landed me in the ER multiple times due to anaphylaxis: asthma, heart palpitations, high BP, frequent fainting, extreme rashes etc. I had to quit my job because I was not functional on any level. Luckily I eventually figured it out.
