Has anyone had an eptopic pregnacy before?

Hello i am 19 years Old I had my first daughter at 16. In that pregnacy everything turnos out fine in a healthy baby. Know it looks like im pregnant but the doctors dont have an idea of whats going on. Blood test and urine test are positive yea they say data does not match and that it might be an eptopic pregnancy. I Just want to know someone advice and what the symptoms might be.
