I had Kyleena for 5 years. For the first 6 months I had painful cramps, but my cycle became very light. I have noticed that I have had increasingly more acne, especially back acne, so be prepared for your skin to be very itchy. Towards the end of having it, I had constant light bleeding through the month and there was no regularity to it (probably because the hormones were wearing off). I have had incredibly bad bloating, water retention, and generic weight gain. I'm a very light build so this weight would normally have been easy to lose. Finally, I had to undergo investigations for ovarian cysts as I was getting all the symptoms for them, and after a bit of research it turns out that Kyleena can be a contributor to the formation of cysts. Overall, I have really liked the Kyleena. The side effects have been fairly insignificant compared to other methods. But just take into account the potential insidious side effects like cysts etc that can happen. I've now switched over to the copper IUD because of these side effects, and I'd prefer to be hormone free.

Was on the injection for over 6 years and was advised to change due to adenomyosis diagnosis. Injection gifted me no periods for 6 years and I’ve still not had any sine changing to coil. Insertion was painful but 6/10 initially. Hot water bottle and pills helped. Cramping did occur infrequently for 2-3 weeks post insertion. Breasts have definitely enlarged and far more tender to touch, feel heavier and unfortunately don’t fit my bra’s anymore. 1st world problems. No issues during intimacy or post either. Other than the cramps, no complaints!

In terms of contraception practically perfect, I react extremely badly to hormonal contraception usually and this didn’t cause any of the negative side effects I usually get from hormonal methods. My periods because lighter and I still have the normal symptoms of my cycle. The only negative (which is quite a big one) is significantly increased pain throughout my cycle, during my bleed and also cramping randomly throughout the month, sometimes when exercising and also two days before my period which I didn’t experience before. I am devastated that this has been discontinued in most places. I think it’s completely inexcusable that there is now no IUS which for most people doesn’t stop their period.
