Ovarian Cancer?

Hi all, 

I hope you are all doing well. I am 17 years old with a long history of breast cancer in my family. Recently though I've been having all the symptoms of Ovarian Cancer such as persistent bloating, frequent urination, lower abdominal pain and so on. I am so worried I just want to cry; I called my drs yesterday and they said it's stress. I called them back up today because my pain was worse and they again told me I need to relax and do some extercsie. I feel like no one is taking me seriously, I have a really bad gut feeling and I'm not sure what to do. My mother tells me not to worry and she doesn't think it's anything bad but I'm not sure. 
 

So sorry for nattering on, 

Eleanor :)
