I'm due today and nothing yet.

So today Feb 18th is when I'm due and it's my first baby. I'm getting really anxious and been getting asked if the baby came yet. Last week at my doctor appointment she did a pelvic exam and said I'm not dilated. I have to go for an ultrasound and I think a biophysical and a NST this upcoming Tuesday then see the doctor the next day. I also been stressed lately and not being myself.
