Bleeding not stopping. Kindly advice me!

My period came on 13th Feb. .For the 1st 2 days periods became heavy & had to change pad after every 3-4 hrs. On 19th Feb. the heavy period still continue & I took Daflon 500 twice a day on 19,20,21 Feb. On 22nd Feb in my ultrasound a left ovarian cyst of size 25*12mm with no fine echos or probe tenderness came. Endometrial thickness was 5mm. On 22nd night I took 1 tablet of Meprate 10mg, On 23rd thrice a day. After taking tablet on 23rd morning my bleeding stops. On 24th also I have taken thrice a day. On 25th I have taken twice a day. On 25th night some blood mixed with some coagulated blood came. Till 28Feb. Sometimes bleeding starts and gets automatically stopped. After that small bleeding continues for 5-6 hrs. and then stops. Till 4th March I was continuing with Meprate 10mg twice a day. From 5th March I have taken thrice a day but bleeding is still continuing. My gynae has adviced to take it thrice a day till 9th March and then leave irrespective of the bleeding.Kindly advice me
