"causes severe migraines in my case, weight gaining (i used to weigh 117lbs after using it for a couple of months i&#039;m 130lbs). i haven&#039;t changed my diet, i am always careful what i eat and i cook at home. i go to the gym regularly i see nothing else i can blame for this situation. i am having mood swings and i get irritated a lot. i never had these symptoms when i was using minulet, femoden or harmonet. i have been taking birth control for 9 years now. i will ask my doctor to change it."
