Telling my Best Friend

So my best friend has made it clear that she does not think it's time for me to have a child right now. Although she has the best intentions with her reasonings she can come off a little judgmental and forceful. Considering we are not expecting our family to be fully accepting at first ( you never know- but they have made some comments) I plan on not telling her or anyone for a while when we actually conceive. I know it's our decision but I will be over the moon when it finally does happen and just the idea that my favorite people won't have the same reaction already bums me out. Anybody else dealing with this?
