Scared to announce that I'm pregnant after giving birth to my first 17 weeks ago

I had my first born 7/31. Wednesday my period was late so I took HMP test and it was positive...pregnancy symptoms have already started (extreme fatigue, lower back ache, and headache). My husband and I are thrilled that we will welcome another child. since I found out I've only told my little sister whom I'm very close to...she was happy for us. I'm just scared how other family members or even friends n co workers will react. I don't want people judging me. Please help or share your experience if you've been in my situation before.
