husband having a hard time..

My husband is in his final year of his degree, due to finish this spring. We are expecting our first baby in the spring as well. He's in the middle of mid terms and did quite poorly on one and is not coping well.. he's not talking to me right now and told me I'll only say stuff so we can have a baby, that his life is moving to quickly and he can't keep up and I'm putting to much stress on him. Which I don feel I am, I'm very supportive. Work two jobs and barely talk about my pregnancy because I know he's stressed. Looking for advice on how to support him through this really. He s a wonderful man and I don't want him to resent me, this pregnancy or baby. My heart is breaking for him.. we don't really fight so I find it extremely difficult when we do and our relationship is generally so good.
