click I have scans every few weeks so it will probably keep on changing. My baby will come when it's ready anyway, maybe weeks before or maybe weeks after my due date. These can be carried out from week 5 or 6 of pregnancy, which is a notoriously tricky time to be accurate on dates.
Measurements at such an early stage aren't accurate which is why they wait for 12 weeks to date you. Expert Jan Steward, who is director of Ultrasound Direct and Babybond, agrees that early scans carry a much greater risk of inaccuracy. We always recommend mums get a definitive dating scan closer to 12 weeks as this will be much more accurate.
Just half a millimetre at such an early stage can change your date by a week. Your week scan will be far more accurate.
The sonographer then said that I was only about 4. Then at the week scan I got an EDD of 15 march, so that early scan was completely out.
Well, you'd think so, wouldn't you. At around 12 weeks you can get more accurate measurements.
By talking to the health care professionals you should get a clearer picture as to what is happening. Thanks so much for your post — we always welcome feedback, positive or negative, as we always aim to make our articles as accurate and as helpful as possible.
We spent a lot of time talking to sonographers before writing this article, so we're surprised that you think what they're saying is not in line with what you have studied. We'd be really keen to know more about your studies — and what you have learned. You're right that we did include 'anecdotal stories' in our article.
We used them to illustrate the key points we were making in the articles but the quotes we used were all centred on the real experiences of pregnant women posting in our forum. Pregnancy math can be a little murky. After all, unless you went the IVF-route, your physician has no way of knowing the exact time of conception.
Because of this, pregnancy is calculated from the first day of your last menstrual period or LMP. From that day, weeks of pregnancy is officially counted, and your doc or midwife busts out the red pen and marks your due date on the calendar. Sometimes, however, the due date may be revised.
It can be pretty difficult to determine a due date using the date-of-last-period method for women with irregular cycles — which is why an ultrasound exam is often required to determine gestational age. An early ultrasound, usually done at about 6 to 9 weeks, can give the most accurate due date estimation by measuring the size of the embryo or fetus.
Researchers had men watch and—erm—react to sexually explicit videos for 15 days straight. Six of the seven videos had the same actress and actor, while the last offered a new copulating couple.
It took each guy relatively the same amount of time to finish the first time they watched one of the six similar videos to the umpteenth time they enjoyed it. The men did, however, finish faster when they were introduced to the new video full of fresh faces. The quantity, movement, and structure—all crucial factors when it comes to sperm health—were improved with the new sexual stimuli.
