Mini pill and weight gaining

I can't tell if this birth control is helping me or not and its so frustrating because i have endometriosis and i smoke so i have to be on a progesterone only pill but ever since i started taking this pill i've had a heat intolerance which they say is not a side effect but it 100% started when i started taking the pill, and they told me my goal is to not have a period and im 2 months in and still am getting my period and ovulating and experiencing breakthrough bleeding and cramps.

terrible experience, dry mouth 24/7, dehydrated, nausea, throat irritated from this pill drying me and heavy diuretic component. made me so tired and depressed and ill caused acne

Honestly this pill helped me correct extreme anemia and I had far less severe side effects than combination pills I’ve tried. It’s been about 5 months and I do still have some irritability and bloating/weight gain from the initial adjustments but it seems to be getting better over time. I was terrified to take any kind of hormonal birth control because I have severe PMDD and it made it worse in the past, but this was actually manageable and I don’t go through 3 different personalities every month
