Hi Miranda-lady

Just to emphasise that if you are peri-menopausal then as Mary G says as well as your specialist - your oestrogen levels will be fluctuating and are likely to be very high around ovulation irrespective of the oestrogen dose you are using.
So I'm not clear what oestrogen dose and delivery method are you are taking/using - are you saying you are on higher than 100 mcg or are hoping to do so? If so what specifically are you hoping to achieve ie what symptoms do you want to alleviate? As you've already been told, during peri-menopause the fluctuations will add to your symptom burden though the added oestrogen is designed to cushion the blow from the oestrogen crashes. I'm also confused because you mentioned decreasing by one pump (ie gel) and then also you mention 100 mcg which is from patches?? Can you clarify please?
Also when you say you've had to take 300 mg progesterone - is this due to bleeding problems or simply due to the high oestrogen dose? Again it's tricky if you are peri. Can you tell us how long you've been on HRT and what your periods were doing in the months leading up to starting HRT - if you had them - this will give an indication of where you are in menopause.
Finally re scans. Ideally of course they should be available on NHS but they are not expensive (relatively speaking - though I realise not affordable for some). Yes they willl be if you have them done through your private specialist, but you don't need to. There is an organisation called "ultrasound direct" (easily found by googling) that will do basic scans very cheaply (and also do other investigations for menopausal women - which cost more) - started off for pre-natal baby scans.
They do a basic endometrial scan which is actually for fertility but I assume you can ask for this even if not for fertility - the website seems to have changed since I last had one. These are £90 but they do a post-menopausal scan which looks at other things which is a post-menpausal pelvic scan and that is expensive - it's £195. I don't like talking about pricing stuff because I realise it's out of reach of many but as you mentioned scans, thought I would say you don't have to pay a fortune....
Glad the testosterone is helping...
Hope this helps also

Hi, thank you for your very kind and thoughtful post! I'm sorry for delayed reply as I've been working.
I'm going to give a little bit more information.
I started on HRT about 16 months ago. My symptoms at the time were long heavy periods ( about 11 days) shorter cycles, and basically no energy, brain fog and feeling like I couldn't do my job anymore. I wasn't sure if I was ' bad enough' to start HRT but read about all the protective benefits of it especially cardiac as my maternal side have had cardiovascular events in their 60s ( Grandmother died from MI aged 67, and mum had 2 small strokes at 67).
I had a telephone appointment with a pharmacist prescriber at my GP surgery. I told her I was sensitive to the contraceptive pill, so she said to start low. (I now understand so much more than I did then.) I was fine ( didn't really notice much difference) until I hit 3 months. I was prescribed 1 pump ( 25mcg oestrogen) and 200mg body identical progesterone cycally. At 3 months, everything came crashing down! I had panic attacks, had intrusive thoughts- remembering things from my childhood, palpitations, anxiety, fatigue, dizziness, skin crawling. I didn't know what was what and whether I was sensitive to progesterone ( I felt a bit better in the middle of my cycle). I tried to get a GP appointment and was told what for continuity I should speak to the same pharmacist but couldn't get an appointment for 3 weeks. Things started to get worse- I left my home and stayed in a hotel, I felt a bit suicidal ( it was more that I thought my family would be better off without me).
I decided to speak to private specialist ( Newson health - the pharmacist that prescribed my HRT actually gave me links to Newson health for the balance app etc, and this is where I saw that I could get an appointment). I saw a great doctor who said I need to increase the oestrogen slowly in increments of 25mcg to 100mcg and to switch to patches as these give a stable, continuous dose. I had to take some time off work as I was very dizzy and still very low but my symptoms started to dissipate. However, things had not completely alleviated. I was still getting palpitations, anxiety and couldn't stay asleep..I was literally asleep, awake, asleep, awake minutes at a time. At this time, the GP pharmacist instructed me that I now needed to increase the progesterone to 300mg to protect my endometrial lining from the 100 of oestrogen. This seemed to make things worse, and it almost seemed that it was out of balance again with the progesterone and the oestrogen. I was told by private specialist that it was ok to increase the oestrogen again so I used the gel to do this until I was on 150mcg ( 1 x 100mcg patch and 2 pumps gel) initially I felt great, but then symptoms started creeping in again. They have never been as bad as what they were when I was on low dose oestrogen and 200 progesterone, but couldn't sleep, itchy skin , fatigue. I increased again ( private specialist aware) to 200mcg oestrogen and switched to patches, and still found that I needed to add an occasional pump of gel in the evenings which seemed to settle me straight away. Testosterone was added in due to the no libido and continued fatigue. My GP refused to prescribe the HRT above the 100 mcg oestrogen but prescribed the progesterone and the100mcg patch and I have been very grateful for this.
I was surprised when the GP declined to prescribe the higher dose initially, but now realise guidelines etc. They referred me to an NHS menopause specialist and I thought ( obviously naively, that they would agree the higher dose, but they have been shocked by my high dose and said they have never never seen a dose as high as this, and I'm risking breast cancer) basically every single NHS menopause doctor I speak to has scared me and I'm now feeling I'm being negligent with my health. I did get some breakthrough bleeding which I had investigated by the NHS and they removed a polyp ( no bleeding since) however the consultant that removed the polyp told me I was high risk for endometrial cancer and took a biopsy of my endometrial lining - the scan showed normal lining) I still don't have the results 2 months later so I'm chasing those, but I presume they have been lost!! I appreciate this is a very long post, but I just wanted to try and get the story down and explain why I'm so confused and don't know who to believe. At all stages the private doctor has still been happy with the oestrogen dose xx
