private treatment

I have been tracking ovulation from august to now using opks and it showed that I'm not ovulating every month at the same time and October and last month I didn't ovulate at all. I have an appointment to get my bloods done to test my horomones and for PCOS but my doctor is rude as hell! I'm 22 and my partner is 25 and he told me I'm too young, to lose weight and when I told him I have lost a fair amount and I am still trying he laughed! I want to get my diagnosis and go private for treatment. The clinic I have looked at and enquiried about is £400 for clomifene stimulation. Will this require all my follow ups or will they cost more? Will they judge me for my age and weight or will they be more understanding? I'm nervous about being put down again or trying to be told that we are too young.
