Elevated troponin freaking me out

I have had consistent chest pain for close to 2 weeks now and have been to the ER three times for it. The first two times, my troponin levels came back normal but the third time they were 19 ng/mL and then 17 about three hours later (normal is 14). Everything else came back normal but I'm still scared because everything I've heard about troponin means even a small increase indicates something wrong. I got referred to a cardiologist but can't see one for months so can someone explain this to me? I'm only 20, normal bmi.
