Pregnancy (Definition)

When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Week on ultrasound picture is gestational age or fetal age.?

Week on ultrasound picture is gestational age or fetal age.?

Both: Fetal age is of course the exact age of your fetus as determined by measurements taken of the baby. Fetuses have different rates of growth or may have problems with growth, so sometimes the measurement age doesn't match the "expected" gestational age. The best "age" is determined by an early ultrasound between 6 and 12 weeks gestation. Accuracy of ultrasound decreases as pregnancy progresses. ...Read more

Is there any relationship between maternal weight gain during pregnancy and gestation period/duration for singletons? For twins?

Is there any relationship between maternal weight gain during pregnancy and gestation period/duration for singletons? For twins?

Not consistantly: Too little weight gain or excessive weight gain could be associated with indications for early delivery (iugr, pre-eclampsia, gestational diabetes, ect). There is no specific concrete direct relationship between pregnancy duration and maternal weight gain. ...Read more

What individual fetal measurement holds accuracy (represents true gestational age) longest in pregnancy (fl, ac, bpd, hc)?

What individual fetal measurement holds accuracy (represents true gestational age) longest in pregnancy (fl, ac, bpd, hc)?

Must use averages: I don't believe that any single measurement is most accurate throughout pregnancy. It is usually the averages that are taken. The most accurate measurements are actually in the first trimester in the way of the crown rump length in terms of predicting the estimated date of delivery. ...Read more

Anteverted,bulky gravid uterus,single intrauterine gestational sac 2.7 cm gestational age 6 weeks 6 days no fetal pole is this OK?or a miscarriage?

Blighted ovum: A gestational sac without a fetal with a gestational age of almost 7 weeks is most likely a blighted ovum (non development of the fetus). Most likely with result is a miscarriage. If not you may need a D&C. Follow up with your gynecologist in 1-2 weeks. ...Read more

Is this normal pregnancy or miscarriage?
report details:

A little early: It sounds like your sonogram showed a very early pregnancy. Since no baby was seen there are two possibilities - too early to see or a miscarriage where the baby did not form. The sonogram will needed to be repeated in 1 -2 weeks to find out which is correct. ...Read more

The crl & mean sac diameter measured during 7th wk of pregnancy gives fetal age:age from conception/implantation or the gestational age:age from lmp?

The crl & mean sac diameter measured during 7th wk of pregnancy gives fetal age:age from conception/implantation or the gestational age:age from lmp?

Lmp: All pregnancy dating is based on lmp. So even when lmp is unknown the age given by crl assumes when lmp "should have been. Ie about two weeks prior to implantation. So a pregnancy is 40 weeks from lmp and 38 weeks from implantation. All studies, all research, all dating, dating by ultrasound goes by the 40 week designation or from time of lmp. ...Read more

Fetal or embryo age: Because there is is no fetus until 2 weeks into a pregnancy (yes, it's an odd but standard way of counting dates), there is no bHCG until after 2 weeks gestational age. Also, the bHCG is not detectable until implantation, because the bHCG needs to be able to get from the embryo into the uterine lining, into the mother's circulation, into the mother's blood or urine sample. ...Read more

Hemorrhage, lower then average hormones, fetus smaller then normal, gestational sac 2 weeks behind fetus. Chances of trisomy or other abnormalities?

Maybe,miscarriage is: More likely. Not knowing how many weeks pregnant you are, it's difficult to give you more specific information. Usually the above consistent with early pregnancy loss. It is best to follow closely with Gyn/OB. Also try to avoid air travel or long car rides, trips in remote areas until this is settled. Miscarriage is potentially serious and can result in significant blood loss, so call 911 4 help ...Read more

Is a 30 mm gestational sac according to a 7.4 weeks pregnant and  13 mm embryo? Is the gestational sac accurate to determine gestational age? Thanks.

Accurate: These figures are approximately accurate and consistent. For example, gestational sac is 27, 29, 33 at 7, 8, 9 weeks gestation while crown rump length (crl) is 8, 15, 21 at 7, 8, 9 weeks gestation. ...Read more

Nasal bone hypoplastic, 3.4mm at 21week scan without any other aneuploidy markers, maternal age 28years, first pregnancy, NT at 13weeks 2.5mm?

Nasal bone hypoplastic, 3.4mm at 21week scan without any other aneuploidy markers, maternal age 28years, first pregnancy, NT at 13weeks 2.5mm?

Needs Evaluation: Nt at 13 wks was borderline high. Nasal bone measurement at 21 wks is rather low since lower range of normal would be 4.4mm. In up to 15% of fetuses with nasal bone hypoplasia there were no other findings of aneuploidy. So, there is certainly a degree of risk here. You may want to consider amniocentesis to be better prepared if there is a problem and relieved if there is not. Good luck! ...Read more

At what gestational age of fetus should the bpd measure approximately 4.1cm (41mm)?

BPD: Well we use more than just bpd to calculate the gestational age. Head circ., femur length, and abdominal circ. Also go into the calculation. However, 4.1cm bpd is consistent with about 17 weeks 4 days. ...Read more
