In November after various symptoms I was referred for an ultra sound and told by stenographer that I had a cyst. Went back to GP for results but he was more interestedly in talking about my depression and medication. As I was walking out the door I asked him about the cyst and was told it was endromitrial but at 5cm was nothing to worry about. I'm sure that is the case but what does it mean? Do I have Endometriosis? Should I go back? I think the cyst has burst - had 48 hours of agony and heavy bleeding. But despite this my periods are still really irregular and last for 3 weeks at a time. Despite having lost a lot of weight my stomach is bloated. I have zero energy. Appreciate any advice, thank you.
