When will menstruation occur if I have reduced the dose of Rigevidon myself? If menstruation does not occur, should I repeat the treatment?

Good morning, for about a month I have no period. I was with this at the gynecologist and found polycystic ovary syndrome (on my left ovary I have a hemorrhagic cyst and on my right ordinary cysts). The gynecologist prescribed me tablets to call the period, Rigevidon I had to take them for 5 days after 2 tablets. On the first day I was unwell (I think after these tablets) so I reduced myself from 2 tablets a day to one. On Monday I took the last tablet, and the period is still not there. When can menstruation occur after taking these tablets? And after a week of finishing taking these tablets and without the appearance of menstruation, can I repeat the ''treatment'' of two tablets per day for a period of 5 days?
