I've tried all the pills out there for BC, but my last resort was the hormonal IUD to stop me hemorrhaging every month. For the last 9 months, I've had 4 UTIs and constant pelvic pain. I've seen a urologist twice, and the hypothesis is that the IUD is drying out not only my skin but my vaginal tissues as well. I wish I could get it out to remove myself this constant UTI type pain, but I haven't bled a lot in the last couple of months. It's a very bad negative for a semi positive.

No major changes but i started to have ovarian hemorrhagic cyst 3 times in the last 3 years. Got scared and now i am focusing on family planning technique, specifically measuring Basal Body Temperature (BBT). So super excited with this. Also using this amazing app called Cosia where I am not only tracking but also getting practical lifestyle tips to make my hormonal balance settle.

Better than copper IUD. Similar in side effects to birth control ring except less effect on sex drive.

I initially thought I was having a positve experience, but after 3 months was diagnosed with Sebohrreic Dermatitis with an extremely itchy scalp and bumps on jawline. Within 5 months I started having noticeable hair loss. I have lost at least 50% density. It is now 11 months from insertion and still shedding drastically. 8 months after insertion, I started having cystic acne which Ive never experienced before. I use to have the Paraguard IUD and didnt have these symptoms

It's ok. No unplanned pregnancy but my periods last for 2-3 weeks and I gained 25lbs in 2 years with no changes to eating habits.

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.

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.
