Who do you speak to?
I'll let you into something that not many medics are aware of. Something to copy down and hand to anyone that even suggests that you 'are too young'. Also ask where they get their mis-information from?
Some girls never see a period: rare but it happens. Some girls have a few bleeds, then they stop. Rare but it happens. GPs don't seem to know that women can never be 'too young' to have peri-menopause: those years when we realise that periods are waxing and waning as well as strange and sometimes debilitating symptoms arrive.
We are supposed to count 12 months from the last bleed: however, Nature can throw a curved ball and another period arrives
so we have to start from month 1. Menopause = last monthly bleed.
Also: nothing is 'only' or 'just'. Bad habits in our language! Mum used to tell others "She's only a secretary, anyone would think that she does the operations!". Without any knowledge of my working practice!!! Or how involved secretaries were with the rest of the Team.
I may have said: keeping a mood/food/symptom diary may be of use. Get onto your GP and ask for a referral to a dedicated menopause clinic: not a gynae as they don't know much either!
