A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed.

Not hearing a foetal heartbeat at 6 weeks is normal and there's no reason for worry. The gestational age of your pregnancy may also be inaccurate. Due to an irregular ovulation pattern or inaccurate estimate of your last menstrual cycle, you may not really be 6 weeks pregnant.

Prior to eight weeks gestation, a transvaginal ultrasound provides by far the best results. Finding a fetal heartbeat on a handheld doppler can take even longer. You may be able to hear a fetal heartbeat with these devices at seven to eight weeks. Or you may not hear a heartbeat until you are 12 weeks along.

The heart rate around this time is at least 130 beats per minute, and it may be as high as 160 beats per minute. From this point on, a normal heart rate can range anywhere from 110 to 160 beats per minute. The heart rate decreases gradually throughout the rest of the pregnancy.

By 17 weeks, the fetal brain begins to regulate the heartbeat in preparation for supporting baby in the outside world. (Up until this point, the heart has been beating spontaneously.) In three more weeks, by around week 20, you can hear your baby's heartbeat with a stethoscope.

It is very unlikely that this would happen on a later ultrasound, but if you are having an early pregnancy scan within the first trimester it is possible, though incredibly rare. The baby's heartbeat can't usually be detected before about 7-8 weeks, but some scans are performed before this.

Most women now get an ultrasound before 12 weeks. A fetal Doppler test normally takes place during your second trimester (weeks 13 to 28 of pregnancy). Some manufacturers of at-home fetal Dopplers say you may be able to hear your baby's heartbeat as early as 8-12 weeks of pregnancy.

A full-term pregnancy lasts between 39 weeks, 0 days and 40 weeks, 6 days. This is 1 week before your due date to 1 week after your due date. Every week of pregnancy counts for your baby's health. For example, your baby's brain and lungs are still developing in the last weeks of pregnancy.

It is very common to not hear a heartbeat at a 6-week ultrasound scan. In some cases, moms-to-be don't hear their baby's heartbeat until they're 7 weeks pregnant. Not hearing a foetal heartbeat at 6 weeks is normal and there's no reason for worry. The gestational age of your pregnancy may also be inaccurate.
