Its very unlikely where a ovulation fails after HCG injection
, even when the scan shows well developed follicle in the right ovary also in the left.
Well with the size of the follicles mentioned in the scan ovulation is much expected naturally and with HCG much more expectations can be made.
I would advice you to get a TVS scan ( Trans vaginal USG ) , with a HD "( High definition variety )As the details in it are reliable , may be the sizes the previous scans mentioned are of cysts, or even misinterpreted .
The endometrial thickness is good , and is not an issue here.
