Don’t know what to do

My husband and I just found out that we are pregnant a little over a week ago and I’m nervous to make a doctors appointment till I feel something. Because we have one baby together but we have had 9 miscarriages. But the son we have together is almost 3 and he was a 23 weeker. And right now he got really sick and he is in the hospital and we have almost been here a month. And I’m nervous what the stress is going to do to me and this baby. So should I Wait a little bit longer?
