Is Primolut N Advisable For Prolonged Bleeding?

hello doctor. i m 37 years old. i m bleeding for 12 days so i went to a doctor and i was diagnosed with PCOS. my doctor gave me a primolut. my bleeding stops after 3 days. then had my period after taking primolut and my period becomes normal. but its been almost a year and it is happening again. i m afraid to go to a doctor again. is it ok if i take primolut again as prescribed before?
