Need advice

So for the last 10 years since I’ve had periods, they’re always extremely painful - I’ve passed out after getting off public transport and had hospital admissions of them thinking my appendix had burst and prepping me for surgery - and pretty irregular. Every doctor I’ve been to has straight up refused to do any teat for PCOS/endometriosis (I’ve also had hair growth on my face and my hairs thinned out ALOT)
