Follow up ultrasound shows new internal vascularity and some angulated

I had my second ultrasound today and it showed new internal vascularity and some angulated margins. They upgraded the mass to a Bi Rads 4. It is the same size 10mm (1cm) as it was on the first ultrasound. I have a biopsy scheduled on 16 September but in the mean time I am nervous/scared of the outcome. I guess I don't really have any questions I'm looking for support more than anything. Anyone have something similar with a good outcome?
