EDITED- I live in Australia so can only be referred to specialist from gp who won’t do it until I’ve had my dating scan

Is anyone else feeling super anxious?? I have cervical insufficiency and cannot get into an ultrasound until the 29th of November. I’m really worrying that because it’s taking so long I’ll miss the opportunity for my cervical stitch at 12 weeks because the referral will take to long. Currently 6+3 and constantly checking after using the restroom.
