abnormal uterine bleeding
"I have been on bc since I was 17. I first had  nuvaring for 4 years and then I heard about seasonique and was excited about having only 4 periods a year the first month (January 2015) was perfect no spotting no weight gain no period. half way into February I started spotting and thought ok this may be normal after two days the spotting stopped... it returned four days later and I continued to spot up until the end of March when it was time for my period! I started a new pack and everything went smoothly no spotting until the week before my scheduled period. started a new pack in july and everything was ok. I started spotting really heavy on July 31st and my period isn't supposed to come until the END of September..should have stayed on nuvaring"
