Honestly I was petrified at first so when they said they were doing lletz there and then it made be worse...I can say though it was fine..no where near as what I thought it would be like.
They squire the dye in which was strange. Didn't hurt but felt weird..and then the gave me a local which I didn't feel at all...when they did the actual lletz you could just feel the heat. It wasn't painful just a strange feeling..I can't explain it other than like having a hot water bottle inside your tummy. I flinched a tiny bit at one point but not because it hurt. Just because i was waiting for it to hurt if that make sense..there was no pain at all for me luckily.
The only trouble I have is now. It is different for different people I know but I was due on my period 2 days after I had the treatment so when I came on my period 3 days after it was heavier than normal...and I have heavy periods anyway..but now I am getting watery discharge (sorry for tmi lol) it's like mouldy water...or like when my waters broke lol so I'm going to call docs on mon just to make sure I don't have infection.
Try not to worry too much..the treatment it's self is not as bad as you think.
You will prob walk out thinking....oh.......it's the waiting that is the worst part..I got my results really fast as well..only waited a week and now it's just smear in six months
Hope this helps x
