Hi Skybie

How scary for you. At 17 weeks it can be very difficult to find the heartbeat. An anterior placenta also makes it harder to find the heartbeat. Try not to worry hun, if you heard the blood flowing through the cord or the placenta then your baby does have a heartbeat.

Your anterior placenta has no effect on how fast the blood flow is. A normal heart rate for your baby is between 110 and 160. Sometimes it may even be a little faster or a little slower than this and still considered normal.

How loud the sound is depends on how close the Doppler is to the blood flow and if there is something between the Doppler and the cord such as an arm or leg.
