Hi,
Welcome to Healthcare Magic. 
I am Dr Ramadevi Wani. I will be answering your concerns.
Happy to know that 
fertility tests for you and your husband are normal.
You are still young. So don’t worry. Give time. You will conceive. Among women  trying for 
pregnancy about 80% of them conceive during the first year and 90% of them conceive by the end of second  year. This is for your information.
Fertyl  induces ovulation. Its effect depends upon type of ovulatory disorder and BMI. When used for 3-6 months, Fertyl induces ovulation in 60-80% of women and about 30-40% of women who take Fertyl become pregnant . Most pregnancies occur in the first 3 months of use.
Some women may need higher dose of Fertyl and some women may not respond to it. So it is necessary that ovulation with Fertyl is confirmed by 
ultrasound at least in the first cycle of its use.
To increase your chances of conception maintain normal BMI, quit 
smoking ( if you're a smoker) and have intercourse at least three to four times in a week.
Take a tablet of 
folic acid daily.
If you have any further concerns do contact me through Healthcare Magic.
