No. There are some kits sold online that claim to reliably determine the gender of a baby after five weeks of pregnancy. These are a scam.
Currently in the US expecting parents usually learn the sex of their baby by identifying the genitals on an ultrasound image. More reliable but risky tests are chorionic villus sampling and amniocentesis. A new study has found that a simple, non-invasive blood test can reliably determine the gender at seven weeks, the earliest of any known method.
Although it would be nice to know earlier, the sex cannot be determined at five weeks, and for the moment the blood test at seven weeks is only allowed in Europe. In the US we have to wait.
At 5 weeks it's a embryo not a fetus. it just grows and can not feel, hear or is aware of anything yet.
At 5 weeks of pregnancy , the fetus is still in the process of organeosis. It will take 3 months for to complete this.
The embryo weighs 1 gram between 5-8 weeks. A fetus is far bigger than one gram.
The size of fetus is 4 to 5 mm at 5 weeks pregnancy and about half an inch or 1.25 cm at 7 weeks of pregnancy. Fetus grows by geometrical proportion with time. So you can calculate the size of fetus at 6 weeks by mathematical calculation. Say the size be X mm at six weeks. So you have 4 mm, X mm, 25 mm in the series, So X squred equals to 4*25=100. X is equal to 10. So the size of the fetus will be 10 mm at 6 weeks.
it is around 29 weeks and 5 days gestation.
Embryo. It's a fetus week 10-38.
No, by this stage the fetus should be clearly visible. The yolk sac is visible from 5 weeks.
You should wait 5 weeks then separate them by gender and start selling them.
Around the 6 weeks point of pregnancy. However not all Dr's will tell you what it is unless you ask.
can a 5 week fetus show on an ultrasound
I understand what you are saying when you say messuring, they messure the sac and it calculates what the size is to get the age of the sac/fetus.
There are two answers to this - one good and one bad. The most probable answer is that you miscalculated and you are actually 5 weeks pregnant. Unfortunately there is a possibility that you did fall pregnant 9 weeks ago and that the pregnancy will not progress. It is possible that either the fetus is not developing, or that the fetus has died which usually means the gestational sac will shrink and appear to be not as advanced as you are.
