Hi Limberley666 and welcome to MM
Can you tell us a bit more about yourself - your age? where you are in your menopause etc? What meno symptoms are you trying to reduce?
Are you on Elleste solo or Elleste Duet?
It does take time for HRT to kick in and do it's stuff. If you've been through the trauma of having a daughter go off to Uni this can be really upsetting but it may be too early to blame the HRT for feeling so low. If you are on Elleste Duet then you are possibly telling us that the pills with both oestrogen and progesterone are the ones making you feel low. If after 2-3 months you find this is the pattern, then you could try a different HRT e.g. Femoston 1/10 which has a kinder progesterone that may suit you better.
I think it is early days and you may need to keep going to see if things settle first. Keep posting DG x
