as i said sue, you will be a mom, and you will get pregnant, dont let your emotions and disappointments rule you. you are being so tough on yourself! keep calm, be positive and take care of your body, do check ups, ask your husband to get checked up, go somewhere romantic, and do not let your mind obsess because then your body will panic and resist and changes, which include conception. you will be a mom and a great one Im sure, just give yourself a break and make your mind, body and self happy so that it can allow you to conceive, this includes weeding out any possibly, if any!, biological needs you or your husband have not thought about, this can be anything from diet to hormones. keep your head up and smile, you will be ok! :)
