Feeling guilty

So, my husbands brother and sister in law lost a baby 2 years ago when she was 8 months pregnant. We were very nervous about telling them I'm pregnant but finally did. He wouldn't even look at is and she said she couldn't give us the reaction she wanted. I've now heard from his mum that they are heartbroken and don't want anything to do with us. My husband says to ignore them all but I can't help feel guilty as my bump grows that We can't do anything as a family. I'm also annoyed that I feel I have to hide my joy of being pregnant. My husband doesn't feel this way but I just can't help it :-(
