My mother had a life long struggle with period problems culminating in a hysterectomy when she was in her mid 30s.
I have suffered from the same thing - can honestly say that in 23/24 years of menstruation, not ONE GP has ever taken my complaints seriously - almost all have been of the 'just get on with it' brigade. Only now, when I have finally paid to see a private gynaecologist, have I had any of my concerns taken seriously and even then, the GP is not supportive of the consultant's treatment (sigh).
It struck me today that poor dd could suffer from the same plight - I know she might not but I DESPAIR of that fact that so many GPs seem completely dismissive of period problems as if they are just a cross that women have to bear.
