Well, according to the menu opposite, it doesn't exist.
I'm a bit surprised that with your problems you are only being advised by a nurse. Given that many GPs are clueless about types of HRT it's not surprising that a nurse may have got her wires crossed.
Can you not be referred to a gynae for some expert help?
Your other options include a complete change of product- from tablet to patch or gel- transdermal forms are safer in many respects although perhaps some drs give tablets as they are cheaper.
At 43 it is just possible that your own cycle is breaking through. The options perhaps include less oestrogen or more progestogen.
If you used an oestrogen either patch or gel- you could then add a progestogen and could choose from several. Norethisterone is one which comes as 1mgs or 5 mgs. Some women have side effects with it. I was fine but as I am on HRT long-ish term ( over 5 years) I've recently changed to bioidentical Utrogestan - but am now having the same issues as you ( bleeding before the end of the course.)
Maybe you need some blood tests to see what is going on because it does sound as if the balance is not right.
