I'm in the same boat as you at the moment, I had my colposcopy on Friday with Lletz and a biopsy taken and am too waiting for results.
Did they give you any idea how long it will take to get them? I think it varies from area to area with time frames, I was told if not heard anything after 6 weeks then to chase them up.
I understand how scared you are about them its a horrible feeling as many ladies on this site will tell you the waiting its tough. I understand too about people bit being able to relate to it as I've told a couple of family members and they don't really say a lot!
My goodness I found the procedure really painful too and I also had the LA, I really found it extremely uncomfortable and have already decided if I need further treatment will be tempted to ask for a GA instead. I fainted during mine too it all got a bit much lol!
Must be hard for you too having these things done so soon after having your baby, but use the fact that you have a wonderful little one to keep your mind off the horrible wait for results :-)
Keep posting on here as there are so many lovely ladies with loads of advice to get you through the wait.
