Hey girlies, Hope you don't mind me posting my question here. I figure you all have more experience with dopplers than us first trimester lot! I got the pink Jumper Angelsounds one with the LCD Display. Although it's ok and I can pick up my hb and babys, it also gives me weird random readings. It can say 60 then 110 then 80 then 140. I assume 80 and 60 are me and 110 and 140 are bubs, but it varies within minute to minute. Surely our heart rates don't change that quickly? Also even when I don't have the probe bit on anything it can give me a reading. Is it a faulty machine, a piece of crap, or are our heart rates all over the place?
