Scanty Period. I stop these medicines?

I have had regular periods all my life. I was doubtful about pcod because of my hairgrowth which seems normal to many peoppe but isnt. I got an ultrasound on 3rd march 2021 and it showed polycystic ovary.I have no other symptoms. All the my blood reports were normal. My doctor put me on myocyst m and utronorm. My period had ended on 3rd march and i experienced bleeding again on 9th march and it ended on 13th march. The bleeding wasn't too much but still there. And yesterday i saw blood stains and assumed my "actual" period came but the blood flow is next to nothing. I have experienced this irregular blood flow and odd period cycle for the first time. Should I stop these medicines? I have changed my lifestyle drastically to battle pcod. Avoided sugar and do a lot of exercise. Can't understand the scanty period. Please Help!
