Mini pill vs Mirena IUD PCOS

i am currently on the mini pill and 7 weeks post partum. i have found that it has balanced out my hormones. before I was pregnant I had hair growth everywhere and now after pregnancy I find that my hair growth is not nearly as much as it used to be on my face area. I don't know if it was pregnancy that helped balance out my hormones or if it's the mini pill keeping me in check. I'm also pretty sure I had PCOS before getting pregnant but I was never checked for it. the mini pill has made me spot like crazy. like full blow forth day after delivery bleeding. it has also made me spot on and off again. does anyone with PCOS know if the IUD balance out their hormones enough to completely get rid of PCOS symptoms. I'm hoping for less hair growth, easier Time losing weight, and lighter periods.
