Does gedarel 20/150 pill cause lower back pain?

I had terrible experiences (bouts of acne) around age 17/18 with higher dose pills like Yasmin. Eventually settled on Marvelon and was put onto Gedarel (higher dosage) when there were stock issues. After 2 years I moved to the lower dose of Gedarel, and had a relatively positive experience with it for around 5 years but things have worsened recently. Side effects have been; spots around chin around end of pill pack, some spotting when taking back-to-back, lower sex-drive. More significant side-effects have been water-retention/weight gain and boob size increase. I am now thinking about coming off Gedarel as I have noticed the side effects have become more dramatic and all other things are equal - my boobs change massively in size throughout the course of a pack of pills, they are tender, and my weight is also massively fluctuating (I assume from water retention - between 55 - 60kg within the month). I am very active and generally healthy, if anything I am less stressed and have a healthier lifestyle now than I did a few years ago, yet the frequent changes to my body are making me feel uncomfortable in my own skin.

I have now taken this for a year and the side effects of this pill are more prominent than my previous pill. I bleed and spot after having a break, my sex drive has decreased and I encounter random strong period cramps randomly throughout the month

Positives: 1. in my last year on this my acne was almost none existent, which was a massive an improvement from when I started it. 2. My periods were also shorter (4-5 days), and my last day bleeding was very light. 3. Not 1 pregnancy scare the whole 3 years, completely protected!! Negatives: 1. no sex drive, I was told this wasn’t a result of the pill but of my mood & life. I can vouch this was incorrect because I’m now 3 months off the pill & my sex drive is through the roof. 2. My mood was always flat, I had happy moments but generally life felt pretty grey 3. My heavy period days were just as heavy & crampy as pre-pill. 4. Exhaustion & lower back pain pre-period. 5. Weight gain & obsession with food, always felt hungry. Overall this pill wasn’t bad as I just got used to the symptoms, but since being off it I genuinely cant believe that I was that shell of a person for the 3 years on it, and the 6 years before that that I was on other contraception.
