Umm idk.. i know I had to tell everyone because I was puking allll the time my whole first 3 months and you can only play dumb for so long lol. I was even worried! I didn't know what was going on, only had an idea. My mom made me take a test in front of her because she knew what was up, she knew something wasn't right because I was vomiting all the time, buf with no other symptoms. They probably already know haha.
I understand waiting I did but I didnt get sick till mid way I would tell immediate family members but your friends can wait I'm surprised one of them didn't already assume or make a pregnancy related joke
I was 6 weeks when I told my family its better to tell them sooner I think you should
