Hi,
My mouth is full of sores/ulcers and it seems to happen every month with my period.
Sometimes are worse than others' like now I cannot eat or speak with out crying 
I have been to my gp (over the years have seen many different ones) and always get given a mouth rinse and sometimes oral thrush cream (sometimes the gp decides that its not thrush related).
I realise this sounds dramatic, but it is ruining my life!
I'm a sahp atm and its hard enough trying to cope with my 18mth and 4yr olds, I would no way be able to get and keep a job as I would have to take 3-5 days off a month!!!
Sorry for the self-pity 
I keep a good oral hygiene routine I just dont know what to do.
