hi doc..what are my chances of getting pregnant this cycle?i am pcos, 1st round of clomid,and last saturday, cd13,my follicles were sizes 21mm and 24mm. my endo lining thickness was 5mm. my doctor didnt give me a trigger shot.so i wonder when probably did i ovulate? and is there a chance for twins? today is cd16 already, am i still fertile?
