Freaking out need encouragement

I guess I’m just looking for some encouragement.. I just found out I’m pregnant with my 4th. I have a 4yr old 2yr old and 9 month old.. this was not planned I know it’s a blessing but and I’m freaking out.. we are in the middle of a move and my husband’s job is also the busiest in the fall time so that makes this even harder.. I haven’t told my friends or family since it’s so early. someone tell me this will all be okay
