Fetal Development

the fetus is in the yolk sac

Sounds like Braxton Hicks contractions. Not to worry, they are "practice" contractions. If they get painful, call the doc right away.

Chances are, something happened to the twin. But since the remaining baby has lots of room to grow, it will probably be born as if it were a single.

Probably over 600 grams (1.3 lbs). Maybe as long as 30 cm (12 inches) stretched out.

Youi can get heart burn at anytime, so it's not a reliable indication.

by the placenta.

Without touching you, no one (father of the baby included) can feel the baby moving. They might be able to see the movement (especially with particularly energetic babies) on the surface of your abdomen but they will not be able to feel it without touching.

Unless a doctor answers your question here, you must ask your own physician. This is a very serious matter you are questioning. -Mame-

a good rule of thumb is to remember to look after your own health. generally you can feel the fetus and if iy's a little quiet for a couple of days theres no harm in ringing a doctor.

The purpose of the air sacs in a bird is to help digest food into the gizzard, and to help it breathe, and stay in the air longer and more smoothly. Hope this helps!

I don't think so! :) More info: As the baby develops and grows bigger, it may seem as though s/he is moving in your back. The baby's limbs and head can push on your internal organs, which can cause a sensation of movement in your back, and even upwards towards the lungs. This can be even more common if the baby is large, or if you are carrying twins or triplets. If you've had an ultra sound, it would have shown if there were any abnormalities, such as any sort of displacement of the uterus. So unless there are no other sypmptoms, or no problems, there shouldn't be anything to worry about. But you should mention it to your doctor at your next pre-natal visit just for peace of mind.

Most likely not, if this was your only intake of an alcoholic beverage; but no more drinking during pregnancy - it is not worth the potential bad outcome

embryonic

no, he is the only son of god

Ask your medical team, they are the ones doing the scans, they should answer your questions. Each baby is individual so answers must be individual.

I'm no doctor but i would say absolutely not!! It can be still to soon. I didnt hear my sons heartbeat until i was almost 12 weeks since it was very faint. I was told because of position, etc that it couldve distorted it. Dont jump and do anything be patient and let nature do its course. I think she will be fine. Best wishes

Generally a transvaginal ultrasound can spot a baby in the womb at around 4 weeks (give or take 5 days)

i heard that it does, then i heard it doesnt. I think it depends on how hard.

There is no true variance in the Male or Female fetus. Depending on how far along in the pregnancy, the heartbeat should be anywhere from 110 to 170 BPM.

During her 2nd Pregnancy a woman has been in the past, delivered of one live birth.

Adding LC1 would confirm that firstborn is still alive!

well if you do not know the answer ,I(that means me)can tell you the answer.the answer is that they form cells,then the cells between your fingers die.

You would need to ask your doctor.

It is entirely normal for only the sac to be seen in the fifth week of pregnancy. In some pregnancies the tiny embryo will just be visible for the first time in this week, but for others it may not be seen until the next week. All that is visible before this is the sac, so it doesn't necessarily mean anything bad as yet. If you are cramping and bleeding it may mean a miscarriage but often this settles down. Your hCG level is another way of telling how things are going. This is measued with a pregnancy test using blood or urine.

Harmful chemicals or viruses that can be transferred from a mother to her developing fetus are called teratogens.
