In a panic

Hi guys
1st time poster here....
So I’m 33 and was at my routine smear today.
After it was done the nurse said she could see a cluster on my cervix and she wanted the doctor to have a look.
The doctor had a look and has referred me to Gynae for a further look and a pelvic ultrasound. I’m panicking so much about this.
My last smear was in 2016 which had low grade changes and I got it repeated which was then clear again.
What could this be.....anybody ever experience this or have this noticed during a smear

Thanks in advance for your replies ❤️
