Welcome to HCM,
After going through your history,your tests are normal this is good, you have not mentioned about your husband he was also tested or not if not then he should be examined to see every thing is fine and apart from routine blood test
his Seman analysis and Ultrasonography
of abdomen and Scrotum
should be done.
If every test of your husband is also comes normal then you must know ovulation takes place 14 days before next expected date of cycle.
There are kits in the market by which you can test ovulation and you can plan sex during those days to increase your chances of conception.
You can take advise from your Gynaecologist if there is any need for any medicine.
Wish you good luck.
