High CA125 Result

Hi all, I am new here.

I am 37 and I started losing weight without trying about 6 months ago. I lost 2 stone without trying and still eating my normal foods (I have MCAS too- allergic reactions to foods and every day life so my diets complicated). 

I have felt full even if I haven't eaten, if I eat I feel extra full, if my jeans touch my tummy I get extremely uncomfortable, I get really bad back and pelvic pain, FUO- fevers without a cause, nausea and struggle to breathe properly. 

I know that a CA 125 isn't conclusive for Ovarian Cancer and endometriosis/fibroids could technically be a cause but nothing I have read that would point to a dramatic weight loss but more of a weight gain. I have had people tell me I have lost weight and that it's good but I feel physically and internally very sick. The dr who's ordered that test is referring me back to my normal GP. 
My result was 56. 
 

I can't get pregnant so I have always suspected endometriosis, hair loss, weight gain and now though my weights dropped, people think it's endometriosis. I feel so unwell and confused. It's just taking me 2 hours to get to town and back which is actually a short walk away.
