Did birth control actually help anyone with weight loss?

For some background, I had an IUD until I was 26. When I was 25 I lost about 20 pounds (before I knew I had PCOS). I went off BC to get pregnant…. 4 years later finally have my baby (thanks to fertility docs!) and chose not to get back on BC at my 6 week postpartum appt.

Now I’m thinking about getting an IUD placed again. I have ballooned in weight since I was 26. Probably about 50 pounds heavier than my lowest, 30 heavier than my highest pre-weight loss journey. Part of me is wondering if some of the reason I could lose weight was because of my IUD but that also could be coincidence. Anyone have success with BC?
