I was more even tempered when on birth control to be honest as my mood shifts and eating issues come from SHIFTING hormones rather than stable ones. So, usually BC would make these things better and a reason why some women take them. Why didn't you take the metformin? I have two really good friends who do for PCOS and it's been a godsend. their pcos symptoms got much better. I get not liking to take medicine, I don't either. But you are at a point in which you are struggling and I'd follow doctor's advice rather than try to doctor yourself. Congratulations on your weight loss. Any is good and it's a start. But losing more I am sure is your goal. Keep at that and again, maybe metformin would help you. PCOS is lifelong to deal with and work around. I'd accept this and just try to roll with some of the things you'll need to do to overcome. Spotting is typical with hormonal issues and agree that it is probably your pcos acting up again. Ugh, I'm sorry about that. I hope it all gets under control. good luck
