My appnt for ablation (for nightmare periods) has come and there's a good chance I'm going to be on a period that day. Will they still do it? Will the ablation be as effective? The info that came with the letter doesn't mention it, nor was anything mentioned at pre-op. I told the consultant that I was bleeding more days than I wasn't, so he knows the problems I'm having. Do any of you 'naice' ladies have any insight on this please?
