Cerazette pill and lower back pain

It's stopped my period completely which is great, not that i had bad periods to begin with but it was definitely convenient. i've become quite irritable since being on cerazette and just overall heightened negative emotions. in the first couple months i had lots of nausea but that went away pretty quickly. overall it's been an alright experience, not bad but not amazing

I started the pill 12 months ago and it was fine for the first 2 months,no pain or anything but then i started bleeding and i havnt stopped bleeding for 10 months straight,it ranges in how heavy it is but it is constant everyday

I was moved from Yasmin to Cerazette by my gp due to my blood pressure being affected. It's my second month and I hate it. I had no side effects from my other pill and was on it for 4 years. My periods used to last 4 days and were regular. Now I'm on day 12 of a very heavy and painful period. Even when I wasnt bleeding I was spotting. My skin has gotten worse, constantly oily and my hair is so greasy all the time. I used to be able to wash my hair once a week (curly), now I have to wash it 2 or 3 times a week due to build up of oils. I have also started losing a significant amount of hair Everytime I brush and wash it. I also lost all appetite and have lost almost 4kg. Also I've never struggled with body odor until now, no antiperspirant helps to prevent it and it's very embarrassing. My entire lower back and pelvis aches and I feel really depressed and fatigued.
