Hi helenart
Sorry to hear about your problems - but your doctor is doing the right thing in referring you on because of unusual bleeding. Far better to refer on too many women who find nothing wrong than to miss one where there is something serious.
In your case - perhpas you could ask what the thickness of the endometrium was when they said "normal" as there is a range for this.
You haven't said what HRT you are on? There are all sorts of reasons for bleeding on HRT - sometimes the endometrium can become too thin and ulcerated from too much progesterone, and this can cause bleeding. Sometimes it is the opposite reason - it has become too thick from too much oestrogen so this causes bleeding. Sometimes it can be due to fibroids or polyps ( not sure if these are normally picked up from the transvaginal scans?).
The same thing happened to me last year. I had spotting after sex and was referred. The TVS showed the lining to be too thick and also they could see an abnormaility on the surface of the endometrium and I was referred for a hysteroscopy (to look at the lining properly with a camera) and biopsy (to check for a condition known as endometrial hyperplasia which can lead to cancer).
I had no anaesthetic but heeded the instruction to take 2 Ibuprofen and 2 paracetamol an houir before the procedure so didn;t feel anything and I was only in the room probably for 15 mins - it was very quick and efficient. Some women have not had such good experiences so I think it must depend who you get and where you are. Perhpas you could google the proecdure and the hospital you are likely to be referred to to see what others said? Maybe there is th eoption of choosing which hospital?
Personally I would not want to have a GA for what is a very minor investigative procedure, since GAs themselves are noit without risk (Ive never had one though so this would make me more nervous than the procedure which didn't bother me at all!). I also gave permission for them to remove a polyp if they found one - which they didn't.
Everything was OK in my case - the abnormailty was a small fibroid which they weren't worried about, but I was so please to have been referred.
I agree with carol try not to worry and it will soon be over!
