I think you are over exaggerating staffs here. Its just been months you have already taken all those teste. Actually to some doctors they would have told you to seek medication after a year. But since you wanted to know what really the problem is. It is not that bad. You have gotten to go through various tests which have told you what the problem is. Since your husband has no issue. Then we shall lay the burden in your side. Concerning unexplained fertility. Yes, it happens. Even with the enhanced and technologized services. There are problems that cannot be easily figured out. Or the doctor cannot really trace where the problem lies. Perhaps till when you stay longer in medication then the doctors can find out where the problem lies. For the time being I feel like you have exhausted all tests. You should just be patient and do what the doctor is telling you.
