I'm sorry to hear this Zara. You have a very good case for being prescribed patches or gel + prog as you are a migraine sufferer and tablet route is not recommended. See the info on this website:
https://www.menopausematters.co.uk/route.phpThis gives indications for non-tablet route. With the current shortage of combi patches your practice should either prescribe an oestrogen patch with separate prog or the gel.
Please go back and make your case. They can override any cost-savings or other excuses and you are entitled to the appropriate treatment of your choice provided the doc can justify on their screen. I would be outraged if my doc tried to insist on my taking tablet HRT. I have NEVER taken any HRT by mouth in 12 + years of using it (exception is a couple of courses of 2 weeks of norethisterone to strip the womb lining).
Femoston has the gentlest of progestogens apart from progesteorne but I still wouldn;t use it with migraines if your preference is for transdermal...
Good luck!
