Do my birth control pills have too little hormones?

Patient: Hi!I changed my birth control pills (Yasminelle) because I kept getting periods even though I ate two packs in a row. The doctor changed them to Yasmin with more hormones. But still I keep getting periods if I eat two packs in a row.(I have eaten Yasmin before years ago and I didn’t have periods when I ate two in a row so this has changed.) Also I keep getting acne around the chin area now even more than usual. Is there still too little hormones in the pills? Should I change them again? Or is there a problem or a change with my own hormones? Thank you!
