I'm currently 19 and have not had my period for 8 months. I have never had sex. My first period was when I was 12 and it was always regular up until two months before I turned 18, in which my period came towards the beginning of the month and towards the end. My period did not come until 5 months after that but when I do get it it is a very heavy flow. I still do get symptoms as if I'll get my period monthly. I do have a lot of hair growth, acne, and weight gain. I went to the hospital once because of really bad lower abdominal pain and they checked for cysts but there was nothing so they told me it could not be PCOS. Can anyone who has experienced this give me some information?
