I am 25 years old. I have never had a regular period. I started when I was 9 years old. The last time I actually had my period was 4 years ago. last month i was bleeding for 1 day then it stopped, i thought i was getting my period, i had the back pain and lower abdomian pain. now this month i started to bleed the same day i started last month, again pain in the lower right back and the lower right abdomin. my sister died at 21 from ovarian cancer. i know i should go to the doctor, which i am working on it now, because i have no insurance and most places wont take you unless you do or if you have alot of money, my question is can you still have your period with ovarian cancer? my sister didnt have hers thats why im not sure if you do or not. my sister found out she had ovarian cancer right after she had her baby, which was 3 months premature. they did surgery and took a tumor out of her then she only lived 6 months. i know i have a good chance of getting it but i am not sure if you can still have you period with it?????could the doctors have been wrong? could she of not had ovarian cancer? i just found out that there is something else called surcoma, which is mistakeing for ovarian cancer.
