Kyleena coil and irregular periods

Struggled to fit the Mirena & so fitted the Kyleena instead - potentially leading to an insufficient amount of progesterone as i continued to have irregular bleeding. After about 12 months this settled down and month on month this has lessened and my cycle continued. However, I experienced consistent cramping like I'd never had before and from 15 months onwards severe & debilitating pain about a week before my period. This is why I had it removed.

I've always had painful periods and the month before I got my coil, my period hurt so much I actually threw up and that's when I decided I would do something about it. I've been on the pill before (rigevidon/microgynon) but it negatively affected my mood, I had terrible anxiety and generally felt horrible all the time so I stopped. When I got the coil, the sexual health clinic I went to used spray anaesthesia, but it still really hurt. The thing is, it only hurt for about a couple seconds, where it basically felt like your insides are being crushed and you're having the worst possible cramps ever (x10). Afterwards, I had normal (period-like) cramping for the rest of the day but they gave me a heat pack which really helped. I had spotting for about 3 months afterwards (yes, every single day) but it was fine and after a while I got used to just wearing a pantyliner every day. I'm really glad my periods are very light now (I've missed it once only) but it's still there. I don't know whether it will disappear or not, but one of the reasons I chose kyleena over mirena is in hopes my periods won't completely disappear, just for peace of mind that I'm not pregnant lol. I have terrible breast tenderness sometimes, like it hurts to even touch, I can't tell if it's before I get my period or during ovulation, but it definitely appears once every month or so. My breasts didn't grow though so that's a bit of a disappointment compared to the pill.... All in all, I haven't noticed any mood changes, I'm still definitely very attracted to my partner, and he doesn't feel it during sex. There were a few times early on when he thought he did, but I got it checked and it was all good, I think he just had it in his head.

Really good contraception however I feel my breasts are sore 3 weeks out of 4.
