Announcing isn't going well

This is my husband and I's first and at 6 weeks we've just started telling close family and friends. So far, it isn't really going well. It isn't going horrible, but it's bumming me out. Here are some of the responses we've gotten to "I'm pregnant/were expecting"
-really?
-congrats (with no smiles)
-it's so early you can't be sure it's true
-we've been trying for months ugh
I am not expecting everyone to go absolutely nuts over this news but I feel like a lot of people have let us down. Has any of your announcing gone haywire?
