Birth control and PCOS

Mi

I have had previously negative experiences with weight gain while on birth control and have not used anything other than condoms for years now. Does anyone have recommendations or positive experiences with being on certain types of birth control with PCOS?

I am in a healthy monogamous relationship and were sick of using condoms but not trying to conceive yet. We are moving in together soon and I feel we will end of pregnant if without a better birth control plan but I am so scared of gaining weight again. I am very strict with my diet and exercise but am still overweight. I work so hard and barely lose weight. it would be so disheartening to lose my progress.
