Pregnant and not excited...yet...??

My husband and I have been married for a year and together for 5 before that. Having kids always the topic that got in our way as a young couple. After 2 years of dating we started seeing a couples therapists. I wanted kids and he didn't. We weren't able to communicate about it on our own and needed some help. After a lot of therapy we were able to come to some conclusions. We would have 1 baby. We would start trying after our first anniversary. Our anniversary was in April, we stopped the BC and prepped for several months of trying and waiting. I got pregnant within 2 weeks.

When I saw the positive on the test I wasn't elated like I had been expecting. I panicked! As did my husband. We just thought we would have a little more time. I am starting to come around a bit but he is still pretty shocked. I want to be the happy excited couple...but we just aren't there. Any advice from others about not having that spark of joy and excitement at the very beginning would be so appreciated.

thank you
