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.

Ultrasounds are pretty ahrd to fight with. If they say your 5 and a half weeks, most likely, you're 5 and half weeks. Maybe sit down and figure out why you think your 7? == Answer== I am so sorry you have to go through this confusing time right now. You could have ovulated later than you thought, your date of your last menstrual period could be off or the embryo is not growing like it should be. One thing you can do is go back for another ultrasound about a week later to monitor the growth. good luck.

Will an ultrasound show heartbeat if you are 6 weeks pregnant?

You could see a heartbeat if they do a transvaginal ultrasound.


Your ultrasound showed that you are 6 weeks pregnant but you should be 9 could that mean you are having a miscarriage?

An ultrasound at 6 weeks should show a fetal heartbeat, if there was a fetal heartbeat you're not miscarrying.. It's probable you estimated your due date wrong.


If you are 9 weeks pregnant and ultrasound results measured 6.5 weeks with a large yolk sac could this be a sign of miscarriage?

This information is correct. I experienced the exact same thing. The early ultrasound is exeptionally accurate in most cases and the baby should measure within 1 week of the estimated age. Your body will most likely miscarry otherwise a D&C could be recommended. The pregnancy will most likely not advance past 12 weeks.


Could I be pregnant with twins if my stomach is getting larger at 7 weeks?

You should have an ultrasound done if you believe you may be pregnant with twins, at seven weeks the uterus is behind your pelvic bone, not yet visible except by trans-vaginal scan.


Why are you showing at 1 month pregnant?

Possible multiple and if none seen on ultrasound you could possibly have vanishing twin syndrome.


You just visited with a doctor you thought you were around 7 week's'pregnant and he measured you and says he thinks you are about 12-14 week's could he be right?

If measured via transvaginal ultrasound he is probably right. That is considered the most accurate form of dating at that point in preganancy. If he is attempting to measure the height of the fundus then it may or may not be accurate. It is very possible to be more pregnant than you realize as many women can spot or have a mini-period while they are indeed pregnant.


Can a horse be pregnant even if she has a negative ultrasound?

Depending on the date of the ultrasound the mare could still be pregnant under certain circumstances. 1) If the mare has many uterine cysts a pregancy could be mistaken for a cyst. 2) If the conceptus is not large enough to be observed at the time of the ultrasound. (ex. the ultrasound is done at what is thought to be day 12 post ovulation but the conceptus is only at day 10). 3) The mare double ovulated and only the younger conceptus, which has gone unobserved, continues to develop. Usually, the veterinarian determines if the mare has double ovulated during the course of each ultrasound. If the mare does not return to heat as expected after a negative ultrasound she should be rechecked for pregnancy and, if open, the veterinarian may be able to determine the rootcause for her failure to return to heat.


If an ultrasound reveals something that looks like the forming of a sac but the blood test came back negative could you still be pregnant?

No; by the time the sac is visible on ultrasound, there would be detectable levels of Hcg in the blood and urine.


Im about six weeks pregnant and you are experiencing cramping Is this normal?

Cramping is normal during pregnancy and could persist. It could also be a sign that the baby is in distress or that you are having false labor pains. You should go get an ultrasound to make sure that the baby isn't in distress. If the cramping is sever then it could be preterm contractions. If the cramping gets worse and closer together you should go straigh to the hospital and have an ultrasound or to the labor and delivery room at the nearest hospital straight away.


Why would a gynecologist request that you have an internal ultrasound if you are not pregnant?

It depends on if you are complaining about pain in a certain location of your body and they feel something, or if they are giving you an exam and you tell them what part is hurting you when they touch it. An ultrasound could possibly reveal something harmful.


Could you be pregnant if myour period is suppost to come every 23-24 days and its the 25th and it hasn't come?

Yes, you could be pregnant if your period is 2-4 days late or even skipped. If you might be pregnant, I would take a pregnancy test or go get a check up or ultrasound.


No Gestational sac appears?

Sometimes you could miscarry very early, but the body doesn't reject the fetus like it should. It does happen. My aunt thought she was 20 weeks pregnant, but when she went for an ultrasound fetus died many weeks earlier
