Im 14weeks pregnant, have a fetal doppler&hearing my baby's heartbeats always on the right side not on the middle line, is that normal ?

Probably yes: Depending on the position of the baby, you might have listen from one side of the pelvis or another. At 14 weeks, it would be highly unlikely that you would have an ectopic pregnancy.

Absoutely: Your uterus can tip in many directions and will not move up out of the pelvis until about 16weeks. The baby may also be lying sideways and not moving position much - yu should be having your level 2 ultrasound for anatomy soon, and that should answer all your questions about where this baby is, but a good heartbeat is very reassuring.

Yes: You may be listening when the baby is located on your right side. Remember at 5weeks the baby is very small. Keep listening as your pregnancy progresses and your baby grows you will hear the heart beat in more places.
