I am suffering from pcod and wanted to conceive. Doctor gave me smart ova for 5 days after that he told me to go for follicular scan from day 8th. On day 8th my follicle size z 10 mm and on day 10 it remains the same. After that he told me to have shot of 5 hmg injections. On day 20 I go for another follicle scan and it shows two dominant follicle in left ovary 20 mm and 16 mm and one in right ovary 19 mm. On day 22 follicle of 20 mm in left ovary rupture but the other follicle become dominant with size of 19 mm and right ovary follicle becomes 22 mm with endometrium thickness of 11 mm. Now the doctor told me to have hcg inj. My question is that if my follicle rupture without any hcg inj why he is asking me for having shot of hcg inj.
