Desogestrel pill and decreased sex drive

Was put on this to help with my severe period pains. It has helped but I'm not sure it's worth it with the side effects. I can honestly say I am depressed. I have zero motivation, zero energy, zero inclination to do anything I used to enjoy. My sex drive has disappeared it doesn't matter because I've bled for the majority of the time I've been taking it. I want to stop but my GP won't try me on anything else until I've been on this for 3 months.

I have been taking Desogestral for just over 6 months. It took 3-4 months of irregular bleeding/spotting before my periods seem to have stopped completely. I do notice that I have had several occurrences of thrush along with weight gain/increased hunger, tender breasts and occasional period like cramping without bleeding. Mood overall has been slightly lower and feel like I am prone to pms symptoms still (teary, low mood) at the time I would have previously been due on. Had been off contraception for several years as combined pill previously contributed to anxiety/depression. Wanted something to control v heavy periods and not impact mood greatly and this seems to be working so far despite some unwanted side effects

Started this pill as I had horrendous migraines on Rigevidon. Was excited to start the mini pill and to not have bleeds in between pills but was I wrong. The first 5 months I’ve had random bleeding- which I expected (but not for over a week straight) I’ve also been heavily dizzy, nauseous and have had 0 sex drive which has affected my relationship heavily.
