I am so sad!!!!

A little background information; my husband and I have been trying to conceive for almost 9 years, but recently we started seen a fertility doctor a few months ago to get help after we both decided that we were going to try harder to have a baby. I did everything the doctor said and I had two mature follicles when I saw the doctor and he said that since I had to really good follicles it was best for me to get a IUI done the next day, which i did. He said he was super positive that I was going to get pregnant. I waited long enough and then got a blood test to see if I was pregnant and it was negative. My husband has no problems with his sperm because he got checked as well. We both were really hoping that this was going to be our month but it wasn't and the my husband was so exited even dreaming about babies and things like that, my heart broke when I saw him so sad. A few days later after finding out that I was not pregnant, we had a fight and he told me you can't even have kids! I was so hurt, mostly because I felt that he told me that just because he was told that his sperm count was really good and had 97 percent motility. Like if he was indirectly telling me that was my fault that we haven't had kids. Of course I told him that he wouldn't have said that if he was unsure about his fertility. I tried to be strong Infront of him and not give him the satisfaction of seeing me hurt, but the true is that later that night when he went to sleep, tears were running down my face. I was crying in silence. I can say I am the strongest person in my family and I never let anything affect me, but this time was different because I got hurt and I couldn't control my emotions.
