I Took Primolut The First Day Of My Period And

I took Primolut the first day of my period and it helped with my heavy periods. I decided to decrease on the amount to 1 tablet on the 5th day. On the 6th day, I decided to stop completely but the bleeding came back heavy. I decided to go back on it and I am still bleeding though not as heavy. This is day 11. should I continue to take it or just stop.. would be bleeding stop?
