How accurate is a conception date that the doctor gives you because I am trying to juggle who the father of my child is i had intercourse a week and a half apart?

It's impossible to be right on the nose and if per chance it does happen it's a wild guess. A doctor can guess approximately 2 - 3 weeks. Unfortunately in your case having sex with two different partners in such a short period of time you won't know the father of baby without a DNA test.

When can a sonogram determine the babys sex?

The most accurate time is between 18-22 weeks. Anything before 18 weeks is more of a guess, and anything after 22 weeks the baby might be too big to see between the knees.

Is it possible to be less weeks than the doctor says?

Absolutely. There is no accurate way for a doctor or anyone else to say exactly how far along you are, unless you were keeping careful records of when your ovulation happened (and tested it with an ovulation kit) and when you had sex. The doctor's assessment is an educated guess based on the date of your last period, and on the size and development of your baby.

Can you take a ClearBlue pregnancy test at 3 weeks and how accurate will it be?

It should be quite accurate at 3 weeks

Your doctor said you were 14 weeks and 1 day making it 12 weeks gestation your second scan at 20 weeks was the same how accurate are these scans?

If two scans early in pregnancy say the same they are extremely accurate. Your pregnancy gestation was 14 weeks and 1 day as pregnancy is counted from the first day of your last period (if you have a 28 day cycle) it was 12 weeks from conception.

3 weeks late on your period but false pregnancy test?

Pregnancy tests are not always right. Plus 3 weeks is quite a bit of time, you should go see your doctor, you will get a more accurate test.

I went to a clinic on and the doctor said I was 5 weeks and 3 days. The next day I went to the hospital and they drew blood and did an ultrasound and said that I was 4 weeks which is more accurate?

You must have given them two different guesses on your last period date. But the hospital would be more accurate.

How accurate are ultrasounds at 16 weeks?

Not very accurate yet, your best bet is to wait until about 20 weeks to get a accurate ultrasound Ultrasounds are always most accurate in the first trimester of pregnancy, within about 3-5 days, in the second usually off by 7-10 days after 20 weeks could be off by 2 weeks and in the third it could even be as much as 3 weeks!

How accurate are sonograms to determine baby's age at 7 weeks?

Extremely accurate

How accurately can an ultrasound determine the date of conception?

Ultrasounds measure the size of the fetus to predict a due date and are usually very accurate, within two weeks, so I would safely assume that it would not be off by five weeks. You can ask your doctor, it won't be the first time he or she has answered that question,I promise. Also it depends on when the U/S is. U/S before 12 weeks of pregnancy are very accurate, plus or minus 2 weeks. After that there are more varibles, babies grow at different rates so they are not as accurate.

Can a doctor tell whether you are 7 or 10 weeks and be positive?

After 3 weeks it should be accurate, take another at 5 weeks to make sure. Or go to the doctor and get a urine test there super accurate!However, sometimes urine tests wont show a positive for certain people, even if you are actually positive. They all depend on how your body works, I'm sure. All people are different.

Is ultrasound scanning accurate enough to reveal a baby's sex at 17 weeks?

they normally wait until 20 weeks, so I don't know how accurate it would be at 17 weeks. I would suggest getting another scan at 25 weeks if you get one at 17 weeks

If you just found out you was pregnant and your first scan said 30 weeks how accurate is that?

Pretty accurate.

No, castor oil is a laxative and could make things worse. You need to discuss this with your doctor.

Can an ultrasound be off by a month in the first trimester How accurate is an ultrasound at 7 weeks?

Well I had an ultrasound at 13 weeks and it was not very accurate. and it will not be able to tell the sex of your baby. Oh by the way, depending on what kind of insurance you have and what hospital you are at you may not get another ultrasound. An ultrasound at 7 weeks is extremely accurate, within 2-3 days. At 13 weeks it will be accurate within about 5 days. It can certainly not be off by a month.
