1st time LLETZ but likely last

Hi everyone!
I’ve just had my very first LLETZ treatment for abnormal cells, but the Dr said due to my cervix being very short, it would not be possible to do another LLETZ and that she wasn’t able to get all of the abnormal (CIN1) cells. Has anyone else been told they have a short cervix or been told they cannot have LLETZ and been offered alternative treatments?
I only had this yesterday (was a doddle, bit uncomfortable and apart from mild tummy ache, I’m absolutely fine), so still waiting for the results, but I’m just curious if anyone else has had to get an alternative treatment if cells haven’t been removed or whatever?
Thanks, Karen
