Doppler tips

Stephanie • Married 2 years, 4 baby losses. Jun 2017, chemical. Dec 2017, missed miscarriage. Jul 2018, ectopic, lost left tube. Nov 2018, missed miscarriage.

I gave in and hubby bought me a sonoline Doppler which should arrive today. I’ll be around 10+4, any tips on using the doppler? I’ve had 4 prior losses so I don’t wanna freak myself out if I don’t find anything.
