Having a hard time getting pregnant! Open to any suggestions!!

Me and my husband have been trying for three years. We both went to the doctor they said we could both have kids. Which was a relief! But nothing is helping. We have tried different positions, taking prenatals, eating healthy.... Nothing is working. I would rather not do fertility drugs or any other option. But if I did that would be my last resource. I have had two miscarriages this year. I don't know if I am too stressed? Please if you know any tricks please let me know!!
