Hi Stockport1965, so sorry to hear you have this nuisance to deal with. If I'm right in thinking you are new to HRT, did your GP explain why he/she is referring you for a scan for the bleeding at this very early stage?
It's fairly common for women to have some bleeding during the first few months of conti (no bleed) HRT use & we are usually only referred for investigation if this goes on beyond the initial 6 months during which the body is adapting to the new influx of hormones,
unless there is some reason to suspect there is another cause for the bleeding.
I agree with Avalon's suggestion to do a search for posts on bleeding on Evorel Conti as this has been raised quite often on the forum. I had intermittent bleeding throughout the 2 years I used EC but it was not thought necessary to investigate this until it continued beyond the first 6 months. Please do a search if you have time, have a look at the 2 links & extracts from them below & maybe discuss them with your GP to make sure you're on the same page?
If you would find it reassuring there will be no harm in attending for a pelvic scan & it's a simple procedure that's not usually uncomfortable but for the full bladder we are usually asked to attend with. I would not expect a hysteroscopy to be thought necessary for bleeding during your first 6 months of conti HRT use unless the scan shows anything to warrant it or as I said above, your GP has another reason to request one.
1) from the Evorel Conti PIL:-
https://www.medicines.org.uk/emc/product/10929/pil"If you get breakthrough bleeding or spotting, it is usually nothing to worry about, especially during the first few months of taking HRT.
But if the bleeding or spotting:
Carries on for more than the first few months
Starts after you have been on HRT for a while
Carries on even after you’ve stopped taking HRT
Make an appointment to see your doctor as soon as possible. It could be a sign that your endometrium has become thicker."
2) From menopause authority Dr Louise Newson's website:-

9. The majority of women who bleed when they are taking HRT do not have underlying pathology
Vaginal bleeding is a very common side effect of taking HRT. Bleeding usually settles within the first three to six months of starting HRT. Every time the dose of HRT is increased, or the type of HRT is changed, then bleeding can occur. Pathology is more likely in women who have heavy and prolonged bleeding and women who have bleeding beyond 6 months despite modifying their progestogen intake or where there is a concern about the clinical presentation or bleeding amount / pattern should be investigated appropriately"
Alternatively you could perhaps email MM's Dr Currie for her advice (I believe there is a small fee for this) which you could then show to your GP if need be.
I hope this helps.
