Has anyone lost weight by starting birth control?

I was recently diagnosed as prediabetic with cholesterol issues & realized a lot of my bloodwork was consistent with PCOS. I also have a history of ovarian cysts & fibroids & irregular periods. I’m seeking a PCOS diagnosis. Anecdotally, I have realized that I lost a bunch of weight when I first got on a birth control that worked for me in my early 20s (Lo loestrin). It was only after switching to one that I didn’t like as much (insurance issues) & then getting off BC completely that I started to slowly gain weight despite a rigorous workout schedule and being cautious about what I eat. I’ve started metformin & am thinking about going back on lo lo estrin but I have seen stories of bc making women with PCOS gain MORE weight and I can’t handle that. So I’m just wondering if it has helped any of you lose weight? By balancing your hormones?
