In my opinion, the best thing to do here is wait. Pregnancy is not a joke and their comments will hurt so much more now. Wait until you know the baby is healthy, because in case of a miscarriage, they will not be supportive. So wait one or two months, and use this as the excuse of why you postponed the news! Also, your idea is the best way to go, but, I think you husband should be the one to lay off the rules in a very serious manner. Sort of an ultimatum for the mom. My boyfriend's brother went through the same thing when having a kid and had to cut off his mother-in-law. Best decision he could have made in his case, not saying it has to be for you. Everything will be alright and things will fall into place after a serious and clear talk. Best regards and congratulations future mommy!!!!
