Just found out we’re pregnant and I feel alone

My husband and I just got pregnant within one month of trying, and ever since I got that BFP I feel completely alone. We went through a bad miscarriage a few years ago and I feel like he has PTSD about it. He doesn’t seem excited or want to tell anyone, mind you I’m super super early, but my family is my whole life. I was so excited to tell my parents, and my grandparents. He doesn’t seem to want to talk about anything baby related and said he’s more private about things and will tell his family when he feels ready. Which is completely fine, but I feel like I have to watch now what I say so I don’t stress him out. I’m excited and want to talk about all of these fun things and I just feel like I have to put my excitement aside to make him feel okay.
