Welcome to HCM.
Fertyl-50 is for better ovulation.Sometime pain is severe during ovulation.
But complete successful intercourse is required from 13th to 17 th day of cycle to get conceive.There are ample chances of getting pregnant.
It is better to go for USG for follicular study
and confirmation of ovulation.Also go for infertility
profile to diagnose the cause of infertiloty.Consult gynecologist for better guidance.
