Daily Doppler use?

Jazmyn β€’ Nursing student. Army wife. Mommy to one sweet angel girl πŸ’•πŸ’š April 18, 2017 🌈 Baby girl due March 28, 2018

Just wondering if anyone has heard anything about whether or not using a handheld fetal Doppler daily is safe? Does anyone know how much is too much? Previously lost my baby girl at 26 weeks. Currently 18w5d and it sure is reassuring to hear her HB.
