How/when do I tell them

So I will start by saying my husbands brother and wife fell pregnant early 2020 and a couple weeks later miscarried, this devastated them as they had been trying for well over a year now with no success and began seeing a specialist

Fast forward to this month they decided to announce they have fallen pregnant again, however this time they decided to tell the entire family the day they POAS.

Well crazy enough this was the month my husband and I decided we were going to start trying. I found out I am pregnant, now I’ve had this conversation prior with my husband before that I didn’t want to announce anything until we were in our second trimester and that our baby is healthy. Now the issue is I don’t know how to go about telling them I am pregnant or the fact that we are pregnant on the same timeframe, much less fear they might have announced too early and might miscarry again god forbid. How and when do I go about this?
