Hi Kimberley
How old are you? Are you taking Elleste Duet, then one that is supposed to give a withdrawal bleed? I presume so. No other meds like POP or Mirena coil? The Elleste Duet conti where you take the same pill every day is designed for post-menopausal women and will prevent bleeds after the settling in period of time. If it is the cyclcal one ( 2 different types of tab) and is stopping your periods then you are most likely to be post-menopause by now.
The progestogen in that HRT is also more androgenic (norethisterone) so could cause hair loss in some women. Also that one can cause side effects such as low mood, tiredness, headaches etc and can give PMS symptoms. if you are on the conti one then this can be very debilitating.
I would change your HRT type - if you want to take a tablet then Femoston is one that is generally better tolerated and comes in two strengths ( the cyclical one) - 1/10 or 2/10 - I would change to the 2/10 which will give you the same dose of oestrogen.
Also you may need other blood tests especially because of the hair and skin - thyroid for example. Also your diet - needs to be good at this stage in your life to ensure no vitamin or mineral deficiencies eg iron, Vit D, Vit B etc
