My sister was given gonal f injection and ovidrel 250 for ovulation and tried to conceive but ended up with periods. Next cycle again she started gonal f injection for 10 days but follicle was only 11.8 my till day 16. So doctor stopped injections, and prescribed primolut tablet for periods. Why this cycle her egg didn't grow? She has pcod. Doctor had told that we can try with iui if needed. Next cycle can we go for iui? Or should she try naturally? What is the chance of pregnancy in first iui? And what is the cost of iui procedure.
