Am I overreacting, or rightfully infuriating?

Me and DH have never used protection yet never conceived, even before getting married. We've been married for 3 yrs and the beginning of this year I reached out for fertility med because obygen dr said I wasn't realising eggs. I only did one cycle(letrozole), cuz the meds where giving me side effects (I felt, I was going crazy). Besides my insurance not covering- so expensive. My cycles have now regulated to 28D. Probably cuz I'm hitting the gym and have lost 20lbs. But NOT pregnant yet. Today I suggested to my DH that he should perhaps go check himself (sperm analysis), he said yes and that was it. I was infuriated but didn't allow for him to notice! Hello, Maybe he could be more supportive or ask more about the subject. So I told him about the price of a clinic I had researched ($250) he said he could buy so many car parts( that's all he cares),,, I couldn't believe it. I guess he's not as anxious as I thought we where. Because he went on and told me he felt like a d**c for causing so much pain, but he wasn't sure he was ready for a baby. I left the  room and came to sleep in the couch. Being a mother is all I ever wanted, I feel so betrayed by him. I don't know what to do!!!
