Hi Doc.. Last June, 2016 I Was Diagnosed As Polycystic

Hi Doc.. Last June, 2016 i was diagnosed as polycystic ovaries and my ob-gyne doctor advised to take rejuvenex, folsyn for 30 days and fertyl 50 mg during 2 to 6 days of menstruation.,on the next month i got pregnant but it was only the gestational sac found inside and no heartbeat, and i had a miscarriage on 11 weeks and undergone dilatation and curettage.. my question is is it ok to still continue taking fertyl until i got pregnant again?
