hi, i had an implanon , but i have not stopped bleeding for 3 months after that, the doctor prescribed me Primolut N to stop bleeding. he said 5mg for 1 tablet one time, 3 times a day for 4 days. the packet came in 30 tablets, which is a dose of 10 days. i searched online, most people get prescribed for 10 days, why did my doctor only prescribe 4 days for me?
