Thank you for your question. As a young healthy fertile couple you have over 85% chance of conceiving in the first year of trying and 90% chance within two years of trying. So you need to have patience if you are only trying for three months and all your tests are normal. Stress anxiety anger worry etc cause difficulty with conception so its best to avoid feeling this way by discussing your plans with each other and the family so there is no pressure on you to produce a child. Best wishes
