Query: Doesn't pick up heartbeat well

I am 34 weeks pregnant and have only heard his heartbeat three times with it. It amplifies every movement of the cord and the clicking on/off button is very loud. I do like that my son reacts to it and kicks wherever I place the amplifier piece so that has been the only benefit. If I haven't felt the baby move in a while I will use this and sure enough he will kick it and I know he is alright. Unfortunetly that is not the only thing I wanted it for- I really wanted to hear the heartbeat. My midwife says not to use it very much because the babies don't like the feedback it produces. Don't order it expecting great results.
