Hi, Thanks for using HCM
When miss a single pill you need to take both the tablet next day with in 24 hr.
If you miss more than 2 pill contraceptive
effect reduces , so need to use other methods of contraceptive for protection.
Brown discharge could be due to hormonal
variation as a break through bleeding. Wait for few days, it will stop, if it doesnot need to consult doctor
Hope this helps you
