Hi, I got period pain for many years. Sometimes it was so painful that I felt sick and vomit. I usually couldn't do anything during the first of my period. But doctors always said it was normal. Last month I met a Chinese doctor, who said I might got endometriosis. Then I searched online and found I had nearly all the symptoms of endo. I also read stories of personal experience and found it usually takes a long time to get diagnosed. I made an appointment with my GP on tomorrow morning. I am wondering how I can convince her to give me an ultrasound scan asap? Any tips?
