I'm 29 weeks and have a cold came in with reduced movement and was put on monitor. When she attached Leads for my heartbeat the alarm kept going off so she turned Down the alarm volume. Now I've just noticed babies heartbeat is dropping to 80s too 100 and no nurse in sight and no alarm to sound fs and I don't have a buzzer to ring:( am I over reacting or am I right to assume something is wrong x
