Birth control-Yaz-skipping placebo question

My question is, would this put me on like a constant state of water mention and bloating since I'm skipping that week? Just keep my cortisol levels up and make it difficult to maintain a normal waistline? Just curious. I think my gyno said it shouldnt affect my weight much but I question that. I shouldn't question her because she's obviously a professional, but what's your experience skipping placebos? I'm on it for PMDD so it's for mood control not birth control lol thanks
