Hi Minnie
It does seem possible the 2/10 was a shock to the system if you are 18 months since last period, but it seems unfortunate to have an extreme reaction so soon after starting - it usually takes a while for hormone levels to build.
We are usually advised to try any new form of HRT for 3 months, though if you felt that bad on it I can understand your not wanting to persevere. Femoston also comes in lower doses: 1/10 (sequential), 1/0.5 (continuous) & an ultra low 0.5/2.5 (also continuous).
As far as I can tell from the BMS website the entire Femoston range should currently be available.
If you are 18 months since last period & there is no reason for you to avoid taking progesterone daily, you could try a continuous regimen, the advantage being that you should not get the withdrawal bleeds that are expected on sequential HRT.
So, you could either persevere with the 2/10 to see if you feel any better in time, ask your prescriber to give you a script for a lower dose or try a different type of HRT altogether. There are quite a few to choose from & you may find a different method, such as oestrogen patch or gel with separate progesterone suits you better. There are also combined patches i.e. containing both oestrogen & a progestogen.
Maybe have a think about what you'd like to do? It should be possible to find a type that suits you, but it may take some trial and error - that's fairly common, I don't think many of us are lucky enough to find the best fit first time around.
See what the other ladies say, keep posting & let us know what you decide to do.
