Hi, am 24years old. I have a PCOS and taking treatment from the past 5months. I was not ovoluated all the times.. So doctor gave Humog injection for 4 days(3rd,5th,7th ,9th days) in my last cycle.. at that time egg was matured an it got ruptured on 20th day. I was expecting that i will get conceive this month.. but i got my period on 33rd day. what would be the reason for that? why i couldnt become pregnant eventhough ovolution occured, egg ruptured.?
