The nausea that's plagued the first nine weeks of your pregnancy may not be gone, but it's beginning to wane. Until now, being a new mom felt a lot like the flu, but something thrilling happens at the 10- week mark that makes your pregnancy seem very real: Hearing your baby's heartbeat for the first time.
Typically, your doctor will use a Doppler device to listen for a heartbeat during a routine office visit. This handheld machine uses sound waves to locate and hear heart tones and then transmits the sound through a built-in speaker. If an attempt to hear your baby's heartbeat fails, it's not necessarily cause for alarm. The position of the uterus, the position of the baby in the uterus or the position of the placenta could all be reasons. Plus, most women have a fat layer above the pubic bone, directly over where a baby would be located at 10 weeks. This can make it difficult to hear a heartbeat, too.
Don't worry if you don't hear your baby's heartbeat yet; in just a week or two your baby will be larger and her heart tones will be easier to locate.
