My daughter has been in Hospital due to a side effect from using Nuvaring birth control. She started using this BC on July 13, 2009 and by Wednesday evening she was put in hospital because DR. thought she was having a seizure. My daughter discontinued the nuvering do to a conversation I had with her on Friday morning. Doctor's. say it takes 72 hours to get bc out of system. Now it is Monday 72 hrs later and daughter is better. She may not get out of hospital for a couple more days byt ladies what it. The drs. had to run all kinds of test before figuring out it was the birth control. This is very scary because at first her systems reflected a stroke and then seizures and then drs. did eeg testing over last weekend and discovered not seizures. Any one else have this problem?
