PCOS - Advice on if its worth going back on birth control to try spiro

For background info I was on Yasmin pill for 12 years from 16-28. I didnt have many symptoms when I started on it but in the last 6 or so years on it I started getting increasing headaches/migraines 9without aura but still bad by the end). I came off it due to this and also curious to see what I would be like off the pill. I found it really difficult for about a year as I discovered I have PCOS, which has led to some weight gain (nothing crazy but for me I was very petite and now my hips/thighs arent as much - though I have started exercising more). Could also be an age thing Im aware. I also suffered really badly mentally coming off Yasmin feeling extremely low and grey.

Note: For anyone feeling like this coming off Yasmin or other pills, please know it gets better!

2 years later and I do have cycstic acne which isnt all over my face but around my chin, cheeks and eyebrows and has left some red marks and lumps I cant seem to get rid of. I want to go on spironlactone but have been told I would need to go back on a contraceptive pill to be able to and Im really nervous about going back on one and it disagreeing with me.

For further context I am 6 months away from my wedding. Does anyone have any advice of best birth control they've tried that doesnt make them put on any weight or make them feel low! They are my 2 main concerns!

Also any skincare that could help if people recommend not doing this and trying more topical (I have been prescribed antibiotics, duac and adapalene - which I current use and helps somewhat but the deep spots will not budge!). Around my period I get quite a few but Im now genuinely thinking is it worth putting my body through the turmoil or bc + spiro?
