When to tell

T

I’m 31 years old this is the first time i’ve ever had a positive test. According to the app im around 6 weeks. I’ve decided to not tell anyone even family until closer to the 13weeks. The only people I’ve told is the father and my sister because I need her help. I’m nervous about people knowing before then because if something happens i don’t want a bunch of people messaging me and talking to me about it. Is waiting to tell anyone the right decision?
