I have a fetal doppler. Not the same brand but similar. You should be able to hear the heartbeat by 10 - 11 weeks by 13 weeks definately. You should be lying down flat becaues thats the best position to be in. Try moving the doppler around to a few different spots untill you hear something. Sometimes if the numbers are flashing its because its calculating the heartbeat, (read the instructions which you probably already have). But definately the best way is lying down. Sometimes it can be different with twins too but just try lying down or have a look if there is a company website which you may be able to ask questions directly to them. Goodluck

you will need to lie down. aim low as your uterus is just starting to come out of your pelvis. try not to worry if you don’t find it just yet. Im 26 weeks and every time the midwife trys to find it i can feel her move away. So even later on with a doctor or midwife it can take a while to find it

I am not sure how much you paid for this but I have patients that buy these things all the time. The dopplers we use in our clinic cost about $600 and usually the ones you buy online are around 1/10th of that which means the technology is significantly weaker and cannot penetrate deep enough into the belly to hear the fetal heart rate. Usually these home dopplers do not work until you are farther along into your third trimester or maybe late in the second. We are lucky to hear the fetal heart rate at 12 weeks with the more expensive dopplers. I doubt you are doing anything wrong i think these companies inflate what their products can actually do and yes laying down would be a much better way to perform the test.
