Ultrasounds

a fetus can medically survive from 24 weeks, so theorectically can survivve then on, so at 31 weeks would stand a better chance than a 24 week fetus, however this does depend on the circumstances surronding the birth, mothers medical history and wellness of the baby, no one will give 100% survival rate even to a full term baby.

Yes very accurate. I personally have never heard of a mistake due to ultra sound. Also scientifically it is impossible to be inaccurate.

Honestly not much. At four weeks the ultrasound tech will mostly likely detect nothing more than what looks like a small black bubble inside your uterus. The baby is still so microscopically tiny that the most you may see will be a tiny grain of rice. It's still even hard to see anything at week 5 or 6. Your doctor will most likely send you for your first ultrasound around week 8 or 9 to see the location of your pregnancy in your uterus, and to determine how many fetuses are present. You won't be able to see much real detail in the fetus via ultrasound until around week 12 or so. That's when you can start seeing bones, individual organs, etc. If you do end up having an ultrasound earlier than week 8 or so, you might be able to see the flutter of the baby's heart...but yeah, week 4 isn't all that exciting :-)

No, a pap smear can't detect blocked fallopian tubes.

There are no known risks, to either the mother or the fetus, associated with the use of ultrasound.

Ultrasound technicians have a very specialised job and to be qualified to become one takes much training. The website UltrasoundTechnician411 contains plenty of information and a list of schools for potential technicians.

Cephalization is a process of formation of distinct head.It was first seen in the group Platyhelminthes.The anterior part of the body first enters into a new environment.Hence a need for development of special modification was required to sense the new environment.Therefore head was developed in the mean period of evolution,with sensory organs,to detect dangers,to detect the prey for feed,search for suitable mates...etc.Hence without cephalization,it is not that easy to survive in the environment.

In general black coffee is safe before any procedure,

unless total fluid input is a part of what they're testing.

It's really just water as far as your body is concerned ... unless you're exceptional sensitive to caffeine (I did run across one poor soul who had convulsions after only 4 cups .... but that's rare.)

Before exercise: Drink one to cups (eight to 16 ounces) of fluid two hours before exercise to make sure you are well hydrated. Then drink another one-half to one cup immediately before exercise. During exercise: Drink one-half to one cup every 15 to 20 minutes during exercise. Although this might seem tough at first, once you schedule it into your regular training routine, you will quickly adapt to having fluid in your stomach. In fact, the fuller your stomach is, the faster it will empty. After exercise: Replace any fluid you have lost. Drink two cups of fluid for every pound of body weight you lose during exercise. In hot, humid weather, you need to drink more than usual. (But do not forget that dehydration also occurs during cold weather exercise

They are not technically doctors. They are called sonographers or ultrasound techs.

If you have had positive pregnancy tests GO TO THE DOCTOR! Babies (and their moms) don't do well with no or little prenatal treatment! On second hand if you are pondering if you are pregnant or something of that nature.. you can go by the time of conception if you know when it was and just count it up. Or you can go from your last period. Most women conceive / are fertile from about 10-14 days after the first daay of their last period. So if you count it that way you should be pretty accurate. Despite the 9 months cliche' a pregnancy actually lasts for 40 weeks or 280 days which turns out to be 10 months but since there are 5 weeks in some of the months the duration of the 40 weeks is stretched over 9 months. If you don't want to calculate it yourself go to any of the baby web sites such as baby center or baby zone and they have pregnancy calculators.... you just have to know your due date or time you conceived. It also gives you week by week pregnancy info on you, your body, and your baby's health and development! Hope this helps! Pam

21 weeks is at the very lowest limit of survival, only one or two babies in the world have lived Each additional day adds to the baby's chances. Babies born under 28 weeks and living also have a very high chance of ongoing medical problems and disability.

because it uses sound waves

and something makes something think that the broken bone is a healthy bone... I'm not really sure exactly what it does I only started doing it yesterday BUT I know they use it because it speeds up healing process

Because your body and the embryo secreat hormones that make you sick sometimes..

Sometimes you can at the second round of ultrasounds (bout 18-20wks) but there are no guarantees that the baby will be in the right position to see or whether what the ultrasound person says is correct - it just a good educated guess.

No, if you are under a lot of stress or you can lift on something heavy and tear the placenta from the wall or any trauma to the abdomen can cause you to miscarry. It is more common to miscarry before you see/hear a heartbeat.

Not on here we cant. But you can always go to Redtube.com or You can find it on the interet.

It is possible to experience bleeding during early pregnancy. However a normal period like bleed is usually not related to pregnancy.

Yes. though not common, you can still have your period while pregnant. Go to your doctor, health clinic, or take a pregnancy test to confirm. If you are pregnant, you will need prenatal care.

Reflected sound waves

Yes. Ultrasound is good at detecting and identifying fluid filled sacs such as cysts.

Not really. Babies grow at pretty precise rates and therefore conception is pretty easy to answer at this early in your pregnancy. You are more likely to have your dates mixed up or that you conceived at a different time than you thought. Yes the date could be off a bit but ultrasound dates are usually pretty clear and accurate on dating embryos. Its all down to the measurements taken of the embryo and last period etc, that give a estimate of the conception date. When an ultrasound shows you are 7 weeks pregnant it actually means you are 5 weeks from conception. Pregnancy is on average 40 weeks from the start of the last period. This is because in the days before ultrasound this was the only date we knew. You don't actually conceive until 2 weeks after this date.

The approximate date of conception was September 15th

Those are called pulse points, the contracting of the beating heart is what is being felt. It is called tactile arterial palpation and it can be felt any place that an artery can be compressed against a bone; at the wrist (radial artery) on the inside of the elbow (brachial artery), groin (femoral artery) in the neck (carotid artery) and pedal pulses in the top of the foot.

The rate of the pulse is observed and measured by tactile (touching the pulse point) or visual means (observing the twitch that can be seen on the outside of an artery) and is recorded as BPM (beats per minute) or called the pulse.
