Saw a consultant NHS gynaecologist a couple of weeks back who confirmed this was def a thing - she’s seeing a lot of women like me, who have v low oestrogen levels despite 4 pumps a day, whereas previously (on old bottles) everything was fine and no symptoms.
she has switched me to Sandrena and I’m now sleeping again, restless legs and hot flushes gone.
I now need to report and take my bottles back to the pharmacy
