Please help urgent

I haven't had my period in 2 months. I'm 16 years old. My last one was the very last week of december. My typical cycle length is about 35. And now I'm at 66. I'm thinking it's stress because I'm a dancer and this month we had nationals and state but I'm not positive. I've had no pregnancy symptoms which is the only reason I think I'm not pregnant. I'm taking a test soon. My only real problem is that my family can't know if I am. And I need to get rid of the kid if i m pregnant. and I have limited money, no job, and my family can't know at all. Someone please help.
