5 months? Your hardly got into the swing of things.
Most of us take 3 to 6 months to get into the HRT.
Given that your able to get the "gold" standard HRT, I would count yourself lucky
A lot of ladies really struggle to get even the cheaper HRT options.
Bare in mind, after 5 months nothing much will have changed and the symptoms that caused you to start may come back with vengeance
Up to you either way, but I'd let things settle for a lot longer, so your body does not end up confused
