4 days overdue and big baby

So at 38 weeks the estimated weight of my girl via ultrasound was 8lbs! I was a bit shocked because that would mean I could expect a 9lbs baby... I'm a FTM and all seems quite scary for me. Now my due date has passed and I've got two sweeps already and no signs she is coming any time soon. I love her so much but I'm so scared. Any other mommy in similar situation? I need some reassurance 😭
