Does the combined pill cause lower back pain?

Been taking yacella for 6 months after not being on any contraception in years due to fears of side effects. Previously been on Loestrin 20 and Rigevidon both of which gave me horrible cystic acne and low mood. Dr recommended yacella as it has anti-androgenic progesterone and I have mild PCOS. So far it has been pretty good! I think my mood is unaffected, skin is great, sex drive unaffected. I have had some slight weight gain in more 'womanly' areas but nothing crazy. My breasts definitely have grown a lot and for the first few months they were quite sore but this has reduced to mild tenderness now. I do experience pain, especially lower back/pelvic, and am emotional during my 7 day break, however I suffered a lot with cramps prior to taking the pill so this is still an improvement for me. Would recommend, especially for anyone with hormonal imbalances like me.

I don't like being menopause at 20's

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.
