So lady’s when is the right time?

Just found out am pregnant am about to be 5 weeks I told my husband already we’re both very happy and nervous hopefully this one sticks and we go threw but we’re not sure when to tell ppl as we we’re pregnant last year with twins and sadly there little hearts just stop beating and we had told everyone back then since we were so happy but we lost them about two weeks after letting everyone know! And now we don’t want that to happen back then we waiting for the first trimester to pass so we thought we were in the safe zone you know? Now am wondering how to keep it a secret and for how long what if I start showing ? This is hard idk what to do honestly I want to tell my family but I know as soon as I tell them they will tell everyone lol but I don’t want ppl to know and then is the baby doesn’t make it have to tell everyone one the reason is I don’t like when everyone will ask what happen how and the whole story makes me more sad having to talk about it sorry for the long rant just I need some advice on what to do?

Thank you gals ahead of time you guys are amazing!!!
