Hi

I am 47 year old. I have heavy periods. I have always found ovulation some months to be painful with some pain at the rear and side. Usually goes after 12 hours. Last month I had some slight spotting on day 14. Pinky/watery. Went  to GP. Looks like I may be iron deficient which I suspected due to heavy periods and me being a vegetarian. I had bloods yesterday and my CS125 blood test has come back at 40. Now I'm terrified. I was being sent for a routine scan for the spotting so hopefully I will go sooner. I wondered if I had endometriosis. Is 40 really high?
