No, it does not mean that you are in high risk of a misscarriage. The Doctor will normally give a due date with an ultrasound but with a variable of 2 weeks before or after the due date. No worries!
Thank you! I also did some other research, and i guess since I just came off the pill, that could have thrown off my ovulation for that month, which could throw off my due date.
That means it is the date conceived (or within 48 hours of). It is never right on, but within a week of. Go by what the ultrasound says. No, if your ultrasound says 17 weeks and 2 days that would be that date plus 2 extra weeks, that is around the time of your last period, unless you have irregular periods or conceived straight after a miscarriage or something. The length of pregnancy is always measured from your last period even by ultrasound.
If you do not remember the date of your last period you can have an ultrasound to determine your due date. More than one ultrasound throughout your pregnancy may be required because ultrasounds are not always accurate. They could be out as little as a couple of days by a matter of weeks.
It is extremely unusual to conceive during a period, but you may need an ultrasound scan to confirm your due date.
GA is gestational age which is how far pregnant you are. LMP is last menstrual period, which is the date of the first day. EDD is estimated dte of delivery (40 weeks from the LMP) The EDD may be changed if the ultrasound gestational age differs from the age by LMP by a lot.
You need to confirm the pregnancy first and a ultrasound will date your pregnnacy.
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.
I think you are going to have to go with the ultrasound on this one.
An ultrasound does not detect when your last period was. An ultrasound measures the size of your baby compared with the millions of others that have been scanned and gives an estimated date of delivery. Up to about 20 weeks of pregnancy all babies are about the same size. After that the size of the baby depends more and more on genetics and nutrition. Counting back 40 weeks from the estimated date of delivery gives an indication of when the last period might have been.
The doctor or midwife will go by the date you started your last period, or by the size of the embryo at the first ultrasound.
When you have a dating ultrasound you are given an EDD (estimated date of delivery) If you count back 40 weeks from this date it should be about when your last period was. If you do not have a regular cycle they may not correlate exactly. 38weeks back from your EDD is approximately when you conceived.
It would be around 8 weeks before the ultrasound date, since you are not actually pregnant for the first two weeks. Pregnancies are dated from your last period. So period on day one, conceive around 14 days after that and therefore '2 weeks pregnant' at that date of conception.
That's only a 10 day difference. The doctor may have just miscalculated the due date. Your due date is 40 weeks from the first day of your last period.
An ultrasound can accurately date a pregnancy. Also, a doctor can give a rough estimate by measuring after the first couple of months.
In the first 8 or 10 weeks, transvaginal ultrasound is very accurate, usually to within 2 or 3 days. After this time period, it becomes less accurate, varying up to 1 week if the ultrasound is performed late in the 2nd or in the 3rd trimester.
Two days late is perfectly normal. A date by ultrasound is only an estimate.
Only an ultrasound scan can give the exact gestation of the fetus and will give you the closest guess to your due date. Most midwives and health proffesionals will take the date your last period began and calculate 40 weeks from this giving you a rough due date, this is only providing your last 'period' was actually a period and not spotting if you may have already been pregnant.
It is possible, yes. After your first ultrasound, the doctor can estimate an exact date for you. Congratulations!
That would be a good question for your doctor. The doctor might suggest an ultrasound. From the ultrasound picture, the technician can estimate how old the fetus is and predict your due date.
You should be given an Estimated Date of Delivery (EDD) from both your last period AND the ultrsound, and they should match. If the ultrsound date is 2 weeks later than the period date it may be that you ovulated late in that cycle. The due dates for my pregnancies changed several times or more during the nine months. I'd follow the latest due date and you'll be so happy at the end if he/she arrives early. :)
If your miscarriage took place in last stages of pregnancy, or if in your miscarriage any kind of surgery was done, you should wait more than six months to try again so that your body comes back to normal position and you also mentally prepare yourself to try for another baby. But if miscarriage occurs in early stages of pregnancy, like within three months, and your bleeding stopped within 10 or some more days, then you can try immediately after miscarriage and there is no need to wait long. Recent studies show that if a woman get pregnant again after a miscarriage within six months, her chances of a healthy pregnancy are far more than those who get pregnant after six months. However you should wait for a normal period after miscarriage and when a normal period comes, you can try to get pregnant again after this period. This is because if you get pregnant immediately after miscarriage and do not wait for a normal period, you will have no exact date of start of your pregnancy as well as LMP. So it is advised to wait for a normal period. My advise is also that you try again after a normal period after the miscarriage, and try immediately after that period and do not wait any more. There is no need at all to wait for more than one normal period. Hope this is the answer to your question.
Zero. Having a period means you've discharged the ova. If you are pregnant this would not happen unless there's a miscarriage. Most women have no periods after they get pregnant. That is why your due date is worked out from your last period.
Yes, if you have a long cycle they can differ. In my first pregnancy my last period was December 17th which made my due date 23rd September. My ultrasound (at 18 weeks) gave a date of October 4th. I had a 36 day cycle. 3 years later my cycle was 28 days and my ultrasound was spot on. An early ultrasound, around 6-7 weeks is extremely accurate. The later in pregnancy it is done the greater the variation as babies are all different sizes.
It is impossible to say as a term baby could be born from 37 weeks to 42 weeks of pregnancy. You need a due date from a period or an ultrasound to have an idea of conception date
Conception date is based on your last ovulation cycle prior to when you didn't get your period. But this can be incorrect if you didn't conceive when you was ovulating. Alternatively you can have a ultrasound scan which will give you a conception date but this can be off by 5 days.
