Pregnancy VS honeymoon

My husband and I had talked about trying to have a baby within the next year, we said we would start trying to conceive around May. He just came home and we talked about taking our honeymoon because we still haven’t. I told him that I would love to take it either the end of this year or beginning of next year but what would happen if we got pregnant? He then acted like he doesn’t want to try to get pregnant this year. I just feel so frustrated because we had talked about it and decided and now he’s acting like he’s not serious at all about it. I just needed to let out my frustration
