Scared....

mamaX2
I got my doppler today and I immediately came in side to use it and I couldn't find my baby's heart beat... I tried for like 15 minutes and I still can't find it. I'm really scared and I don't know what to do and my husband works in a shop so he can't always have his phone on him... Should I call my midwife or should I just wait it out relax and try again here in a while?
