not sure how to take his reaction

So I had gotten pregnant and thought my SO would be ecstatic, but he kind of just said "Are you sure?" and didnt put much thought or any emotion at all, not even a yay finally. Soon to find out at a 5 weeks I miscarried January 25, 2018 and it's like it never even happened. No sorry, crying, not even a hug which ticked me off because after 2 years of us ttc and this happens... but my friend got pregnant about 2-3 weeks before I did. Found out she miscarried about shy of 2 weeks after I did. I told my SO and he was like "that's so sad" and very sympathetic. I wasnt able to get an untrasound soon enough but I showed him hers from when she was as far along as i was and told him that this is how far i was but he just kind of looked and looked away with no response...I'm still taking this news hard and emotional spirts. Idk what to think. ...Last I knew he wanted kids as bad as i do
