Slynd pill and weight gaining

I have taken this pill for four months to help with endometriosis symptoms. Previously, I was on Eloine for about a year which worked greatly for me with minor side effects, but changed out of precautions due to having had two or three migraines with an aura. Within the first month of taking Slynd, my headaches became more frequent and intense (to such degree that I need to see a neurologist). Without changing my food habits, I gradually gained 8 kg in the four months of taking Slynd. I also have felt my mental health has been negatively affected by depressive feelings and mood swings. I am a mental health professional and was very surprised at this side effect, given my self-care routines and emotional regulation skills are usually optimal. I also developed adult acne, which I would have been ok with if it was the only side effect. The acne and weight gain have negatively affected my self-esteem. One good thing I experienced on Slynd is that my endometriosis cramps were less intense and that I was able to take this pill continuously, thereby skipping my periods and making endometriosis symptoms more manageable. As a result of this, I had more energy to work out.

Lowered my Bp to the point that I’m off meds. Only mini pill that I haven’t bled through.

Loss of sex drive and mood swings were especially bad for the first 4 months or so. It since has gotten better, but I don't think it's back to normal. I have gained about 10-15 lbs since I've started the pill and I have also bled (more spotting than normal period flow) around 5 days during the second week of the pack and never (or so I recall) during the last four days of the pack. While I'm spotting I have pretty constant cramps, which I didn't have before.
