Hello,
Welcome to ehealthforum
If you have been trying to conceive for 5 years and have not been successful then there could be any underlying pathology as fibroids,PCOD,thyroid disorder,endometritis etc.
You require a detailed pelvic examination along with investigations as USG scan,Blood tests and Hormonal Analysis.Also your partner's Sperm Analysis would be required.Kindly visit a Gynaecologist for detailed evaluation and required investigations.
Take care!
