how do i use pv in a script that has a seq for loop

I have a script that has a for loop in it that runs a specific amount of times, and I was wondering if it is possible to implement the pv command in my script to add a progress bar. Here is my code:

for i in $(seq 1 10000000); do
    echo "iteration ${i}"
    #rest of for loop
done

log:

iteration 1
iteration 2
iteration 3
iteration 4
iteration 5
iteration 6
iteration 7
iteration 8
iteration 9
iteration 10
*and so on

if anyone can help me with this, any help would be greatly appreciated edit: i changed the code a bit:

for i in $(seq 1 10000000); do
    echo "iteration ${i}" | pv -l
    #rest of for loop
done

and it gave me this output:
