Fertility test advice

Moriah

My husband and I have been trying to conceive for 3 years now. We had a miscarriage a year and a half ago. I've gotten ultrasounds and an MRI done and the only thing off is my uterus is shaped slightly different. I have also had blood work done and all is normal there. What is the next step? I feel so unbelievably discouraged and sad. Do we check his sperm count next or should I do more tests?

Thanks everyone!
