Last 2012, i was operated because of ectopic pregnancy, they cut my left fallopian tube. then after that, i found out on my check up that i have polycystic ovaries so my OB advised me to take althea pills+metformin tablet for 6 months to regulate my menstruation. after which My OB advised me to take clostil for 5 days to help in ovulation, is there a big chance that i will be pregnant?
