So I did a really stupid thing and bought an angelsounds doppler I found the heart beat on it last week twice not for long but I found it I've tried it today and can't find it I hear the occasionally whooshing noise but no heartbeat I'm 18+4 weeks am I just being dramatic and I should put the doppler in the bin or do you think that there could be a problem, I haven't felt any movement yet either please someone put my mind at rest
