Hello! I had a Lletz in 2020 and I am 18 weeks pregnant.
Just like you, they offered me consultant appointments and I was really scared but when you think about it, this is actually a good thing as it increases the chances to find any issue very early :-)
In my case, I had a first scan and some swabs at 14 weeks where they told me my cervix was a bit short (3cm) but not short enough to worry (<2.5cm). I then had another scan at 16 weeks where it was stable, and I have my next scan next week at 19 weeks.
The consultant was very reassuring, telling me that this is for prevention, and if my cervix shorten, there are things they can do, like giving a progesterone supplement, or doing a stitch.
The little bonus is that despite these scans being internal, my consultant always does a quick abdominal scan too to show us the baby, which is nice. From what I read, most consultants do this so if it makes you feel better, maybe think of it as an additional way to see your baby?
Good luck, and keep us posted!
