Desogestrel pill and lower back pain

Since i was 18 i tried 7 different contraception methods (pills and nuvaring). However i had diagnosed migraines, but none of the OBGYNs i was seeing though this was a concern. Now i am 24 and i finally found a competent OBGYN thanks to my friend. She was the only one who really looked through and studied my medical history and suggested taking desogestrel for my ovarian cysts and corpus luteum cyst, which were more rare occasion. I started my second pack today and i’m scared to jinx but the last two weeks were amazing. The first two weeks were a hell, i had bleeding for quite some time and then spotting for a week or more. Now i don’t have any spotting, my sex drive is the same, i am happy and i feel like i even started to lose weight. I am planning to update my story next month to see how my body would feel on these pills.

It feels nice not having a period. But I’ve noticed I’ve become more spotty , I sweat more also & get thrush

i’m not sure if it is normal but i have been on this pill for 3 months. a week into the taking the pill my period finally came back after around 100 days. since then ive had very irregular periods often bleeding for extended periods of time and also spotting more often with the periods being closer together. i have also experienced much more mood changes as i have felt somewhat more depressed on this pill. this might just be my experience and might also be influenced by the fact i am still going through pubity as i’m 16 yet i still can’t stop thinking that something is wrong .
