Desogestrel pill and spotting

i have definitely noticed good and bad side effects just after a month of taking this mini pill, one of the good ones is i have lost weight without changing my diet or physical exercise, as well as an increased sex drive and enlarged breasts! (a positive for a smaller chest sized girlie like me) however i have also experienced negatives such as very drastic mood swings that change rapidly, as well as uncomfortable vaginal dryness and more bloating than usual. i am also spotting quite frequently but not heavy whatsoever, i only have to use a tampon a day to prevent the blood from ruining my nice underwear

I was constantly bleeding and around the third month I started seeing a pattern emerging that essentially flipped my natural cycle: three weeks of bleeding, 4–5 days off, three weeks of bleeding, a couple of days off. It had a bad impact on my mental health, made me feel exhausted most of the time and killed my sex drive, ultimately leading to a breakup.

I wanted birth control to calm down or stop my painful periods. I was put on denestrogel as my gp wasn't comfordable putting me on oestrogen due to migranes. the first two weeks were great, then i started getting cramping but no bleeding. all that i saw was brown discharge for another week before i started bleeding. i didnt stop bleeding for the three months I was on it. completely ruined my sex drive as I was bleeding all the time and all of my underwear got ruined. I couldnt use a pad or tampon as the bleed wasn't heavy enough. it really started to affect my mood that i stopped taking it halfway through my third month on it because i was getting so distressed was really dissapointing as I saw so many good reviews on it and loved that it had a 12 hr forgetfulness window.
