Hello, I'm 30 + and with three years of married life. I have PCOD on bilaterally on both ovaries. I have irregular periods from my adolescence. Last year after taking clomid and Hucog 5000 injection I conceived, but at 7th week it happened missed abortion. I have done SIS and the tubes are patent. This year according to my doc, I have taken clomid again and Hucog 5000 injection ( when follicle size was 21x18 mm). But still after three days of taking the injection, it's not ruptured. Is there any chance that the matured follicle will no be ruptured at all? Please give me the information. I'm very worried about it and feeling so helpless. Thank you.
