How to tell my family?

I am 14 weeks pregnant and I am trying to hide it as much as I can because I lost my other kids to cps so my family doesn’t know and I was getting ready to get them back but then a charge popped up so I thought it would be better to get this charge taken care of then go back for my kids they accused me of malnourishment on one of my twin boys when they was 3 months old which my twins was preemies and the one they said was malnourished was not growing right in the womb and his brother was taking food from him and he had acid reflex really bad so he wasn’t keeping anything down or gaining weight like a normal baby his age I went to the doctors multiple times and to children’s hospital multiple times and that’s when children’s accused me of malnourishment I know soon they will find out when I start to show but I don’t know how to tell my family or my other kids when I can’t hide it anymore? And I’m starting to think how my kids will feel because they want to come home please no rude comments now my twins will be 2 years old in November
