Pain and bleeding 6 months after lletz

Hi all. I had a lletz procedure (CIN 2) back in February and am due another smear next week. It wasn’t an easy ride as the biopsy before hand gave me an infection and I was admitted for a few days and then had 5 weeks off after the lletz.

The last week I have had mild bloody dishcharge with what almost seems like the scabs that come off after the lletz and today I have been in lots of pain, like period cramps. 

I’m worried that some more cells may have grown back, but have read on here it could possibly be scar tissue?

any experience/advice appreciated x
