I got diagnosed with PCOS almost 7 years back and a couple of years back my ADHD got worse. I don’t know how it happened but it did. Now i realised, after reading your posts that i had taken emergency contraceptive pills at those specific times in the timeline when my ADHD started getting difficult to handle. I fell into depression and had a loss of apatite and libido. The moment I broke off the relationship i started feeling better and started losing weight as well. But my ADHD didn’t get better. O think all kinds of birth control has this effects and it’s important to use protection during sex and not just to keep safe from stds and getting pregnant but also our own mental well-being depends on it.
