Ultrasounds

There are two types of pregnancy tests available though your Dr, blood and urine. Blood tests can show positive 8-10 days past ovulation and urine tests are most reliable 14-16 days past ovulation.

It is unlikely that they would be that far off. They're often off by a couple of days or weeks, but not usually 1 1/2 months off. I strongly suggest that you speak to your doctor about it for more information.

Absolutely not. The later in pregnancy the less accurate the scan. The first two giving a due date of October 2nd will be correct and give you a conception date of around January 9th.

An ultrasound does not determine the date of conception it compares the size of your baby with the size of other babies at the same stage of pregnancy. It said my first was smaller than I expected, about a week out, but he was born on the date the scan suggested weighing over 8 pounds. With my second (twins) it was spot on, they were born 4 weeks early, one of average weight and the other rather small. with an ultrasound it determines your due date due to the size. go to your last period, and minus 2 weeks. say you are due on the 30. minus 7 days, which should be the beginning of your last period. since your last period, on the first day is 2 weeks from ovulation, minus 14 days. now the day is the 9th. 5 days before and sometimes 1 day after is when you are fertile. that is your conception area. 30rd - 7days = 23rd - 14 days = 9th. this is the day you ovulated. From the 5th to the 10th you were fertile.

i belive its called paroxysmal artrial trachycardia

Pretty good. Early in pregnancy the average heart rate is 163. In later pregnancy between 110 and 150 is normal but it can still rise and fall with exercise.

At 5 weeks 5 days I had no fetal pole detected, just an empty sac. I had the same at 7.0 weeks. However, at 7.5 days a fetal pole and heartbeat could be seen. From talking to friends during the "waiting" time, it appears that most women do not see a fetal pole until about 6 weeks minimum.

Arrange a hospital appointment and get checked out.

The above answer is actually incorrect, Yes you can tell the sex from 12 weeks onwards if the sonographer has researched and knows how to use the nub theory which is basically the angle of the dangle, every baby has a nub that does look like a willy up until around the 16th week but it is the angle of the nub which allows you to determine gender for boys the nub has to be pointing up on more than a 30 degree angle and girls lower, the girls nub tends to be flat and in line with the spine there is lots of information on the 'nub theory' which claims to be 95% accurate at 12/13 weeks and in my own personal experience having two little girls and seeing there nubs both me and sonographer agreed they were girls hope this helps :)

I highly doubt it...here is a website that has a picture of a baby at week 17...

Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.

The prep for a renal ultrasound is nothing to eat or drink after midnight. The exception is that you must have completed drinking approximately 32 oz. (or have a completely full bladder) of water/clear liquids by 1 hour prior to your test time. You should start drinking about 1 1/2 hours before the procedure and finish drinking by 1 hour prior. Once you have started drinking the fluids, do not use the bathroom until after your test.

Are you sure they didn't say 6 weeks + from conception, at this stage an ultrasound is unlikely to be 10 days off unless you have a long cycle. I had a 36 day cycle and my LMP was December 17 and my EDD from that was September 23. My scan date was October 4 which turned out to be the date my son was born.

Sometimes the baby turns and causes you not to be able to hear the heartbeat.

There are many over the counter pregnancy tests offered such as EPT or FirstResponse. Each claim a similar success rate of 99 to 99.9% accuracy. These tests, however, are not the final say. The doctor's office has more accurate ways of testing a woman for pregnancy and can confirm a pregnancy in the most reliable sense.

It is in the inside of the cranium (head).

Normally toothpastes contain a fluoride such as sodium fluoride and also a whitening agent such as bicarbonate of soda.

If by fetal age you mean age from conception, yes they do because a pregnancy is always measured from the notional last period, even if you don't know when it was. I.e. from conception, pregnancy is 38 weeks, whereas from the LMP it is 40 weeks. An ultrasound does not add or subtarct form your due date. One method of calculating the EDC (Estimated Date of Confinement) is to calculate from the first day of the last menstrual period, since not all women ovulate on a regular basis, this is not always accurate. The ultasound calculates the EDC by measuring the size of the babies head, the bone length, crown to rump length, etc. None of these mentods can say exactly when the baby is due. Even if a woman only had sex one time and it is known exactly when she conceived, there is no guarantee she will deliver on her due date. The EDC is an estimate as to when the woman will deliver, the fetus will usually deliver within two weeks of this date.

if they can see anything it would be very accurate, the problem is at this point the baby is usually in the head down fetal position and there is not alot of room in there to move around and being able to see anything at all in that area can be difficult, i had an ultrasound at 32 weeks and the tech said i could offer her all the money in the world and she wouldn't be able to tell the sex at this point (i already knew at 20 weeks, its a boy)

good luck maybe you're still in a position you can see

Ultrasound is non-invasive and therefore lower risk.

It is the use of high-frequency sound waves to visualize the interior of the body, typically to "see" the fetus.

Amniocentesis is the extraction of amniotic fluid from the uterus via a big needle.
