Infertility

I’m 16 and I have a very high chance of getting ovarian cancer. I’m just young and scared, my mom won’t talk to me about it because she also had it after she had my siblings and I. But I’m showing signs a lot younger (my mom showed signs when she was 35 and I have since I was 14) I’m just nervous and scared because i was born to be a mother, I have a older boyfriend and all he talks about is having a future with me but my mom always tells me not to tell anyone, not even my closet friends. I just need support because I never get a chance to talk about it.
