get it checked,I bleed but I've the number of the gynaecologist who tells me to call him anytime IF its unusual bleeding for me.I know whats normal,I'm 65 so been bleeding a very long time and I knw when its oit of the usual range .
I saw him before christmas for a long bleed that had lasted weeks ,all OK .Its a symptom of my weight loss interfereing with the dose.Try not to stress,lots of us bleed and its nothing to worry about but best to get a doctors opinion.Oh and by the way there was no suggestion of me coming off HRT .
