Yasmin pill and lower back pain

I’ve been taking Yasmin for just over 2 months now (skipping periods). About a month and a half in I noticed I’ve been extremely irritated, not particularly angry but it’s made me have a really short fuse. Unfortunately for me, it has made my boobs grow pretty significantly and made them super tender and sore after wearing sports bras etc. I’ve noticed a slight weight gain which also sucks as have been losing weight pretty steadily a few months before starting and I feel like I’ve lost that progress. I haven’t really noticed a change in my skin, i think it’s a little bit worse but maybe it’s purging? I’ve skipped both periods since starting, and noticed I was having some cramps after 1 month. I’ve had extreme cramping the last 48 hours and thought I was dying, and ended up passing a decidual cast (which I’ve never experienced before) and have had pretty heavy breakthrough bleeding the past 48 hours. A month ago I probably would’ve stayed on the pill but after everything I think I’ll be swapping to something else..

I have found my experience with Yasmin ok. I like that my mood is much better than on other pills and I feel more like myself, but I have completely lost my sex drive and experienced other negative symptoms unfortunately

It seems with this I lose and gain weight easily, overall loose weight I don’t have much appetite and I’ve lost a lot of breast fullness which is a shame
