Hello dear,
I understand your concern.
There are both male and female factors contributing to
infertility like :-
Female factors:-Hormonal abnormalities like thyroid abnormalities,
progesterone insufficiency,
polycystic ovarian disease (PCOD),diabetes,high prolactin hormone levels ,tubal block etc.
Male factors:-
low sperm count or poor quality of semen or any ejaculatory problems etc.
So all the above causes in both the partners should be evaluated.
If both of you have all normal findings and you have regular cycles then it is called unexplained infertility.
Don't worry.Avoidance of stress and anxiety regarding pregnancy is very much important as they cause hormonal imbalance and delay fertility further.
Practice regular intercourse to increase the conception chances.
Relax.You are on correct line of treatment.
Fertyl helps in inducing the ovulation.
And
intrauterine insemination also has successful results if natural pregnancy fails.
There are also many advanced techniques available for infertility presently.
Hope this helps.
Best regards...Dr.Srilatha
