To tell or not to tell

Ashley • I am 24 years old engaged to the love of my life. We have 1 daughter n a step daughter.
When ttc do you tell friends n family or keep it a secret? My fiancé doesn't want anyone to know at all so it is a surprise. But I hate not being able to talk to friends n family about it. Some of my family would be so happy to know a baby may be on the way. I can't stand it I'm lieing to everyone when they ask when are we gonna have another baby.
