My wife was suffering from pcos but got period in last 3 months regularly after taking medicine as per doctor's advice. She performed home pregnancy test after missing period (lmp -08.01.2020) and found negative result. She has taken regestrone 5 mg twice daily for 5 days (21.02.2020 to 25.02.2020) as per doctor's advice to get period. But she hasn't get period. Now she again performed pregnancy test (on 14.03.2020) and now she found it's positive. What will be effect of regestrone on the fetus?
