Yes according to this website it does http://www.mayoclinic.com/health/prenatal-care/PR00112 At week five, your baby is 1/17 of an inch long - about the size of the tip of a pen. This week, your baby's heart and circulatory system are taking shape. Your baby's blood vessels will complete a circuit, and his or her heart will begin to beat. Although you won't be able to hear it yet, the motion of your baby's beating heart may be detected with an ultrasound exam. With these changes, blood circulation begins - making the circulatory system the first functioning organ system.

∙ 15y agoAt 5 weeks there is not even a fetal pole visible by ultrasound. I am an Ultrasound tech and it is normal not to see a fetal pole/heartbeat at 5 weeks. At 5w6d to 6w3d you should begin to see a fetal pole first then a heartbeat.

How big should you be at 5 weeks pregnant?
You shouldn't be big at all. At five weeks pregnant you have just developed an embryo. An ultrasound typically will not even be able to detect a heartbeat yet.
How big is the embryo when you first hear its heartbeat?
how big is the embryo when you began to hear its hearbeats?
When does the heartbeat of a foetus start?
The heartbeat starts when it's a embryo and at week 5-6.
Are there ways to kill a embryo 5 weeks old?
yes. An abortion pill
Can you tell your having triplets at 6 weeks pregnant?
No No Not true. I am living proof, got an ultrasound thinking that I was 8 weeks pregnant to detect a heartbeat, only surprise I was in fact only 6 weeks pregnant with three amniotic sacs with three embryo's meaning triplets. However, I have to wait yet again to detect any heartbeat activity.
When I was 6 weeks along with 1st baby the doctor heard a heartbeat. Now at 7 weeks he says there is no heartbeat and it is probably a miscarriage. There is no blood and no pain?
When you have a miscarriage it can be like that. The embryo just dies and wont come out and you have no symptoms. To get it out you will either be given medication to start cramps or they will give you a D&C and scrape the uterus.
If you are three weeks pregnant with twins but the doctor saw only one heartbeat on the ultrasound and your hcg was 3045 will the other baby develop a heartbeat eventually?
Three weeks pregnant is a week before you miss a period so it is impossible to know it is twins. If you are three weeks after conception, (5 weeks pregnant)it is still early to see a heartbeat.
I am only 5 weeks why doesn't my baby have a heart beat?
The baby is not developed enough to have a heartbeat.
When do you first have a heartbeat?
When does a baby have a heartbeat? A baby's heartbeat can be detected by transvaginal ultrasound as early as 3 to 4 weeks after conception, or 5 to 6 weeks after the first day of the last menstrual period. This early embryonic heartbeat is fast, often about 160-180 beats per minutes, twice as fast as us adults'!
Can a embryo grow without a heartbeat?
No. It is dead with no heartbeat. Actually it does, since an embryo has no heart. It is the mother's heart that is keeping the embryo alive. It isn't until it is a fetus until it has a heart. While its heart it not being fully used and has a hole in it that keeps it from fully working, its heart does beat.
What week can you hear a baby's heartbeat?
A embryo has a heartbeat around week 5-6 but you can hear it more clearly around week 8.
Can you be pregnant and the doctor not see that there is a baby there?
No. They usually do an ultra sound and that will show the fetus.Yes, during the first few weeks of pregnancy, the embryo is so small that it is hard to see, even with an ultrasound.The heartbeat is usually visible in an ultrasound after 7 weeks gestation.
