Missed period. After taking meprate?

Hello, I'm 27 years old and I m diagnosed with pcod back in 2021 and I have taken treatment for that and later on I conceived and had a baby in 2023. And almost a year ago I started having irregular periods (my cycle went to 43 to 45 days) so 6 months ago I consulted my gynic and re started pcod treatment for 3 months. My cycle has become regular once I started the course and it was fine for 6 months. Now my last period was on 2nd March and I missed my period on 2nd April, I waited till 17th April and after negative pregnancy I consulted my gynic. She suggested tsh, prolactin and a scan. Both tsh and prolactin are within normal range and scan showed pcod. So she prescribed meprate 10 mg twice a day for 5 days and it's been 6 days since I completed the course but no sign of period. What should I do? And why is my period still delayed even after taking meprate?
