Nearly time for my 12 month smear - anxious

So it will soon be coming up to have my 12 month smear. Last year i was diagnosed with HPV and low grade cells, i had a biopsy which found CIN1 and a tiny bit of CIN2, no treatment was given. Im really scared that when i have my smear it will show up that i have severe cell changes. Ive been getting a bit of back and hip pain lately and more discharge so thats also making me incredibly anxious.
