Hi, I've been taking diane for 3 years and switched to althea for the next 3 years, so 6 years in all. Just last month, I decided to stop taking pill. After finishing my last pack, I did not take the pill anymore. After a week of not taking the pill, I had my period again until now which is 10 days already...Most of the time, the blood is brown in color. Is it normal? Please advise. Thanks
