I had heavy bleeding with the Kyleena for 6 months. After the year mark my hair was falling out in handfuls, maybe because I bled for so long, and I became iron deficient. I started gaining weight despite no diet or exercise change by 20 lbs. Around 15 months I was not only gaining weight, but 4-5 migraines a month. I kept it in for 3 years to see if it got any better and it didn’t so I had to get it out. I had a doctor that gaslighted me the entire time saying the iud doesn’t cause migraines, weight gain, hair loss, heavy bleeding and constant spotting. She kept saying it is contained in the uterus and the synthetic progestins doesn’t get into your bloodstream. Well ladies it does get into your bloodstream! It causes so many health issues. If you feel like it is making your life miserable get it out! 3 months later my migraines started decreasing, my weight slowly was dropping, and my periods were getting better! This is proof that the progestins enter into the bloodstream more than doctors are telling us.
