At 5 weeks pregnant there should be a heartbeat.

No, this is incorrect. The baby's heart starts beating between 6 & 8 weeks of pregnancy. If a pregnant woman were to read this and then have an ultrasound at 6 weeks an have no heartbeat yet, she might be devastated. Get your facts straight, please.

At this time the embryo is still smaller than the size of a raisin. Low on the sides of the head are two folds of tissue that will become the ears. Although not completely developed, all the major body organs and systems are formed. The heart also forms, and it begins to beat on the 25th day after conception (about 6 weeks after the last menstrual period), and a heart beat can already be detected.

Would an ultrasound be able to tell the difference between a fetus at 4wks3days and 7wks3days from conception your scan showed a faint flicker of a heartbeat which date is it more likely to be?

Absolutely a scan can tell the difference within 3 weeks at this stage. The heartbeat would be visible at both 7 and 10 weeks (which you would be pregnancy wise). Measurements are taken to date the pregnancy so you need to ask the doctor/tech/nurse how many weeks pregnant you are.


Is it possible for baby to be alive even if no heart beat is detected during an ultar sound?

If you were still very early on in pregnancy, then yes there is still a good chance that everything is fine. Many ultrasounds don't show a heartbeat until 7 weeks. Everyone is didn't, some people will see the heartbeat at 4 or 5 weeks, while others don't see it until 6, 7 or even 8 weeks.

No Gestational sac appears?

Sometimes you could miscarry very early, but the body doesn't reject the fetus like it should. It does happen. My aunt thought she was 20 weeks pregnant, but when she went for an ultrasound fetus died many weeks earlier
