Week By Week Fetal Development Chart
My dr. Said i'm 5 weeks (counting from the 1st day of my last cycle), but that in reality i'm only 3 wks. Many websites offer week to week details on fetal development. Which week should I read? 3 or 5?
Is there a big difference in fetal development and maturation if a baby was born at 31 weeks compared to 35.5 weeks?
yes: You are talking about a difference of about ten percent and the difference between the two gestational ages is significant. Most 35 weekers will do ok from a lung perspective but many 31 weekers will have resp. Issues. Both are preemie but one is much closer to term. ...Read more
Great question!: Caffeine crosses the placenta and may have fetal effects - including proarrhythmic tendency in the fetal heart and untold consequences in fetal brain development. Consumption in moderation is not contraindicated during pregnancy, however studies are lacking to assess your excellent question, namely what effect that has on the infant's character and neurolodevelopmental outcome, if any. ...Read moreSee 1 more doctor answer

Too many to list: You basically build your baby using what you put into your body. If you consume toxic substances, baby will show the effect. If you avoid such materials the baby has a chance to grow to the full potential of their genetic abilities.Each of the materials has specific negative effects, & sadly, many ignore the issue anyway. ...Read more
What causes turner syndrome, noonan syndrome, & the rare klippel-fell syndrome? What happens during fetal development that causes these conditions?
A genetic accident: During formation of the egg or sperm can leave out an x chromosome in either one. A fetus whose genetic make-up includes the germ cell missing a chr. X has turner syndrome. One of 8 different genetic mutations is passed on to a fetus by 1 parent or happens spontaneously to cause noonan syndrome. 2 related genetic mutations are passed on to the fetus by 1 parent to cause klippel-feil syndrome. ...Read more

Ultrasound result: single live intrautrerine pregnancy,presently cephalic,20weeks and 5days gestation,oligohydramnios fetal ascites..what can i do
See perinatologist: Its frightening to have an ultrasound that gives news that isn't perfect. Oligohydramnios means that there isn't enough fluid around the baby. You can help make more fluid by drinking lots and lots of water and getting enough rest. You need to see a perinatologist to find out why. This is a doctor who concentrates on complicated pregnancies to find out why. Best Wishes! ...Read more
Metaphysical questio: Your question is metaphysical and i cannot answer to those ramifications. I will say, though, that maternal sorrow, anxiety, depression, stress do affect the pregnancy adversely and increase the risk for small babies, preterm birth and cesarean section. A healthy, optimistic mood is essential in all aspects of life, including reproduction! ...Read moreSee 1 more doctor answer
Non-significant: The outcome in migraineurs when compared to controls is non-significant in cases of miscarriage, congenital anomalies, toxemia and stillbirth.

Ultrasound: Many moms do find reassurance in US as they can actually see their developing baby moving around and the physician can check anatomy. They aren't required though.

8 weeks pregnant ultrasound showed 4 weeks.fetal pole n yolk sac not seen gestation sac seen is everything alright?its my first baby
Most likely, YES: Ultrasound is superior to your period in dating early pregnancy. A gestational sac is the first sonographic sign of pregnancy and appears about 4 1/2 weeks. Next is the yolk sac at about 5 weeks. The fetal pole with a heart beat at about 5 1/2 to 6 weeks. So, yes, it appears your pregnancy is progressing normally. ...Read more

U/s:single intrauterine gestation sac & fetal pole crown2rump 0.53cm 6w3d + or - a wk no yolk sac/ hb. Nxt u/s i'll be 11wk.Should i worry?Dating off?
A little concerning: More information needed but if a fetal pole is present and can be measured, then a fetal heart beat should seen. If there is just a gestational sac with no fetal pole, then the size of the gestational sac matters. A gestational sac that measures 18mm should have fetus with a heartbeat and if not, then a miscarriage is most probable. Good luck. ...Read moreSee 1 more doctor answer
On the sonography report, it was notated "intrauterine gestation 17w 6d." is this the actual fetus size? Does intrauterine gestation mean time of fetus in uterus?
Yes -relax.: Intrauterine means that the pregnancy is where it is supposed to be: inside your womb. The estimated gestational age is the result of measurements of the size/weight of the fetus and is pretty accurate before 20 weeks in predicting your due date. Congratulations! ...Read moreSee 2 more doctor answers
I am meant to be 6weeks and 4 days pregnant. Went for a transvirginal scan which only showed a gestation sac and yolk sac no fetal pole. Is this indicating a miscarriage . ?
Not necessarily: While it is possible that you are having a miscarriage, it may be that the pregnancy is just too early to see the fetal pole on US. Rescanning you in a week should reveal what you are looking for. In the meantime, watch for signs/symptoms of miscarriage - cramping, bleeding, etc. Good luck! ...Read moreSee 1 more doctor answer

Textbooks, library: There are many, including some very good textbooks. Depends on how detailed you want the discussion. "the developing human" is a good one, though it has been around awhile.

Touchpoints is best for baby development. ...Read more
Single intruterine fundal gestational sac is seen with no detectable fetal pole development at 7 weeks 4 days will the baby survive looks like 5weeks?
Less likely: So, the first assumption is that the dating is correct. If you are truly 7+4 weeks, there should be both a fetal pole and a heartbeat. But for various reasons you may be only 5-6 weeks so worth repeating ultrasound to make sure ...Read more
