It sounds like an error in the coin stamping process. When coins are minted, a round, blank piece of metal is punched out of a strip of flat metal. The flat planchet (the minting term for a blank coin) is then moved along until it is between two steel dies that have the coin's reverse images engraved on it, one side of the die is pressed downward onto the planchet as it rests on the opposite die. Sometimes these dies will come unbolted and rotate or become misaligned and produce a coin with a crooked or off-center image. Coin collectors love these "error" or mint fault coins. It is certainly worth something to the right coin collector. I would put it on eBay and see what happens.
How does a foetus get its oxygen?
It comes from a temporary organ called the placenta. The fetus is connected to the placenta by the umbilical cord. From the placenta, which is normally attached to the uterine wall, blood, oxygen, and nutrients are transferred through the umbilical cord to the developing fetus.
What is the role of the uterus in the development of the fetus and the placenta?
The uterus is where the fetus develops and the placenta connects the uterus to the fetus.
When can you feel a baby kick when he or she is inside the mothers womb?
The baby is mostly active starting around 4months, when you will feel like there are bubbles or butterflies dancing in your stomach. These kicks get harder as days pass.
Is the baby's heart beat the same as the mothers?
it depends are you asking for a baby in the womb or outside the womb? if outside it could be i guess but if inside it can run anywhere from 140-170 slower heartbeats are usually boys and faster are girls. for ex: boy;154 girl;171:)

What is the first organ formed in the fetus?
The heart is the first organ to develop in a fetus. Together, blood and the circulatory system, that is powered by the heart, form the first organ system.
At what day or week of pregnancy does the human fetus normally start to produce pancreatic enzymes?
No any study has been conducted as such. This is more or less a theoretical question, as foetus has nothing to digest except few epithelial cells. So probably at the end of the first trimester fetus can secrete the pancreatic secretions. Fetus consume the amniotic fluid and urinates the same continuously. After birth only baby needs the pancreatic secretions to digest the colostrum or the milk.
They grow for a few days then they could fly now like their mummy.
Do baby geese have umbilical cords?
No. The young of all birds including geese come from eggs which are laid by the mother, so the baby is in the egg outside the mother for some days before the egg is hatched.
It means go to the dr. Don't chance health of yourself and possibly a childs.
It probably means you have uterine fibroids.You often get a "fluttering" feeling with these.The best way to find out is to go to the doctor.
Does the baby become less active during the last 3 weeks of pregnancy?
It truly depends on the baby, how big the baby is, and how much room you have in your womb. Typically, a baby becomes less active because it is harder for him/her to move around. My little girl was not typical though. The movement did not change at all even as the time drew closer. I am an average sized woman, and with how large my belly was, I thought maybe I had a lot of room and she was smaller than average. (Mind you, my last ultrasound was at 6 months, so all size estimates were just that, estimates.) So, imagine my surprise when she finally arrived and she was a whopping 8lb 2 oz, 21 inch long baby. I must of had a lot of room in there for her to do her somersaults!
How developed is the foetus at 6 weeks?
Up to 8 weeks after fertilization embryo is present which is unborn baby in early stages while foetus is an unborn baby in uterus in later stages of development (after 8 weeks till birth).
What is the earliest that you should for sure hear or see the fetal heartbeat?
Hi,
I had scan a week back.And at that time i was 6 weeks and 3 days pregnant and the tech showed me the heart beat of the baby.I don't have a scientific answer but i replied based on the experience.I .But it depends on individual.
Can the weight of carrying your 9 month old baby harm your current pregnancy?
Under normal pregnancy circumstances, it is commonly advised for a pregnant woman not to lift anything heavier than a gallon of milk. Also, do not lift anything that is awkward to carry that is about the weight of a gallon of milk or heavier. This is especially true beginning the second trimester. As your belly grows, you already become off-centered with the extra weight in the front, and carrying awkwardly shaped or large items, no matter how much they weight, can be dangerous in that it increases your risk of becoming off balance and falling.
However, if you have a high risk pregnancy, they will not want you to lift anything at all... outside of your fork or hairbrush.
Now, if your 9 month old is at an average weight, it is okay for you to carry her, provided you are not a high risk pregnancy. You should not carry her for extended periods of time, nothing outside of moving her from spot to spot if no one is around to help you. However, do not bend at your back to try to pick her up from the floor. Bend with your knees... or better yet try to get her up onto a couch first so that it will be less stress trying to get a good hold on her.
In any case, you should still consult with your doctor in case he has any special instructions for you.
Of course, everyone is someones heart, that's why we call it love.
What is the difference between gestational and conceptional age -- why the two weeks?
The simple answer is that gestational age is calculated from the first day of the pregnant female's last menstrual period, while the conceptional age is calculated from the time of ovulation. In a normal menstrual cycle, the first date of menstruation reliably occurs about 14 days after ovulation, accounting for the two weeks' difference in gestational age and conceptional age.
And now for some background information. Both gestational age and conceptional age are terms used to describe the age of a fetus during a pregnancy, particularly the age at delivery. But as you've observed, they are off by two weeks, such that gestational age is about two weeks greater than conceptional age.
Gestational age is how much time has passed since the first day of the last menstrual period (LMP). Conceptional age is how much time has passed since conception (fertilization). Conception is presumed to have occurred on the day of ovulation. The difference in time between the LMP and ovulation is two weeks, which accounts for the two week difference in gestational age and conceptional age. While individual female's menstrual cycles vary by length, timing, etc., a female reliably begins her menstrual period 14 days after ovulation.
If you have fetal pole and heart beat but you are 12 weeks pregnant?
A fetal pole and heartbeat are signs of a healthy pregnancy at 5 ½ to 6 ½ weeks.
If there is a heartbeat, you have every reason to think you are having a healthy pregnancy. I would suggest maybe there is some miscalculation of the dates and further testing needs to be done; a serum hCG level, with a repeat in 6 days and an ultra-sound repeated in 3 to 7 days, should clear up a lot of questions. Below are the specific things to look for in the first trimester that will indicate pregnancy is progressing normally.The first trimester weeks 1 through the end of week 13.Weeks 3 -5 Since LMP - (Fetal Age 1 - 3 weeks): Between day 6 - 12 after conception, the blastocyst will imbed into the uterine lining, marking the beginning of the embryonic stage. At this time the thickening of the endometrium (uterine lining) is evident.After the embryo implants into the endometrium, hCG starts to rise 18 - 7,340 mIU/m is a normal level and it will continue to double every 2 to 3 days. Before an embryo is visible, the yolk sac can be seen inside the gestational sac - late in the 3rd week.
Week 6 Since LMP - (Fetal Age - 4 weeks): A vaginal ultrasound could possibly detect an audible heartbeat at this time. The embryo is about a ½ inch in length.
5 ½ to 6 ½ weeks is usually when either a fetal pole or even a fetal heart beat by vaginal ultrasound is detected. The fetal pole is the first visible sign of a developing embryo. Normal hCG levels are 1,080 - 56,500 mIU/ml.
Week 8 since LMP - (Fetal Age - 6 weeks):Everything a full grown person has, your embryo now has (in miniature) The bones are beginning to form, and the muscles can contract. The embryo is at the end of the embryonic period and begins the fetal period.
A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heart beat, is an indication of a healthy pregnancy. hCG levels will run 7,650 - 229,000 mIU/ml at 7 to 8 weeks.
Weeks 9 -13 since LMP - (Fetal Age - 7 to 14 weeks): The fetus has grown to about 3 inches in length and weighs about an ounce. The fetus can make a fist, and the buds for baby teeth appear. The head is nearly half the size of the entire fetus.
The hCG levels will peak at about 8-12 weeks of pregnancy normal levels will run from between 7,650 - 288,000 mIU/ml.
Why do babies ball up inside the womb?
babies ball up while in the womb because there is not much moving space and it then seems to be a bigger space if they are smaller.
