Hormonal IUD and irregular periods

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.

Do not recommend if you’re prone to headaches or migraines loss of appetite from being nauseous

Honestly, the Mirena in my opinion isn’t bad at all. I have increased migraines but with OTC pain meds like Tylenol or ibuprofen, it helps a lot! I highly recommend this IUD just for the fact that it did lighten my period and lessen the cramps BUT I will add, it’s been continuous spotting since I’ve gotten it which isn’t a huge deal, just very annoying. Then I don’t know about yall, but the sweating…and over heating is crazy. This 4th of July I had to be taken by ambulance to the ER because I overheated so bad I passed out for over two hours, completely unresponsive BUT good vitals. I’m a very healthy 23 year old so that was completely unusual for me, I live in the Midwest so the heat can be a killer but it’s never EVER made me pass out or even dizzy, let alone unresponsive. So following with that, I wouldn’t say it’s a bad IUD, minus all the inconveniences. I haven’t gotten pregnant at least! Oh and to add, my sex drive is annoying my partner, he threatened to give me an ice bath last night to be exact😅
