Hello ! I Was Given Provera To Stop Long Period

Hello ! I was given provera to stop long period and just took it for 2 days and bleed stop then I stop taking provera 10mg . After 2 days bleeding comes back , I then took provera 2 times a day . It changes my bleeding to bleed at daytime and nothing at night time. I did go back to the doctor she gave me provera 10mg to take 3 times a day but I'm on day 3 still the same !
I'm worrying and can I use primolut tab to stop the bleeding cos it's too long ?
