Choosing the right pill for me, help!

Hey ladies,

I have been on the pill for 6 years now and I still don't feel I've found the right one. Lots have had negative side effects and I have tried about 10 different brands. I am currently on a low dose pill and it is mostly ok but I am having a really hard time losing weight on it and I don't always get my period which makes me anxious. Any recommendations on finding the right pill for me? Not sure how I feel about iuds or implants or anything also I have PCOS, All answers welcome please and thank you!
