20 mm Fetal heart rate: 164 bpm, the other one is 33,7 X 18,4 Fetal length: 16,7 mm
Yolk Sac: 5,9 mm Fetal heart rate: 166 bpm
Also embryon1 age is 10w3d but embryon 2 is 9w2d. I'm very concerned. Are those differences ok?
The next ultrasound is in 10 days and the wait is killing me.
Whenever your doctor does your early ultrasound, do they go by your fetal age or gestational age to get your due date? I was reading online that gestational age goes from your last LMP, and your fetal age is the actual estimated age of your fetus. And it kinda confuses me on which one the doctor goes by when they do the ultrasound.
I did a search and found this regarding what an ultrasound would show at 5 weeks on *****************.org
"Week 5 - Gestational Age (Fetal age 3 weeks)
Development
The gestational sac is often the first thing that most transvaginal ultrasounds can detect at about 5 weeks. This is seen before a recognizable embryo can be seen. Within this week, at about week 5 ½ to the beginning of the 6th week, a yolk sac can be seen inside the gestational sac.
m 9 weeks pregbant based on the last LMP. My sonograpger/obs stated my fetal age is 6w5. Gestational maturity by CRL 12.6mm, there's a fetal pole and a yolk sac but FETAL CARDIAC activity not demonstrated. I'm going back for another US in 2weeks. It's a long wait! Is their hope somebody? Can't stop crying and asking God hard questions.
The use of drugs of the tetracycline-class during tooth development (last half of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can cause retardation of skeletal development on the developing fetus.
5-7 weeks... Im just wondering if you are counting from the fetal age(from conception) not the gestational age(from first day of last period) as there is about a 2 week difference... so im thinking that your gestational age would be 6 weeks 4 days which would make more sense for the timeline.... and would make more sense to be able to see the fetal pole and possible the heartbeat at your next appointment....
oh and i want to add that 85% of normal hCG levels double every 72 hours...
Normally a gestational sac with a yolk sac appears at about 5 weeks (calculated from your last missed period date) of pregnancy and can be well visualized by 6 weeks on a transvaginal (through a vagina) ultrasound (so it can be missed at 5 weeks), when you can see a fetal pole too. Fetal heart beat usually appears by 8-9 weeks. This is why it is best to repeat the scan a week or two later.
At times the sac appears but there is no baby inside. This is called blighted ovum.
Usually the 5th week you will see the gestational sac but maybe no fetal pole. By week 6-7 you should see the fetal pole and if you're lucky a heartbeat. By week 8 you should get a heartbeat. So if you are only 5 weeks it sounds like your development is very good seeing both a fetal pole and hb. Did he mention what the heartrate was?? I am not sure what the "likely" fetal pole means because if there is a heartbeat then there is definitely a fetal pole there!!
What confuses me is the fetal age and gestational age. Gestational age is 7weeks 4days, but fetal age 5weeks 4days. I am told you do not hear heartbeat until 6weeks. Sometimes not even until 12weeks.....I am confused. But' both my primary ob and another on specializing in multiple pregnancies want to see me in a month which I am told it usually is 5-7days for a case like mine.
i had some spotting and got scared also and had a transv us at 6 weeks 5 days and only saw a gestational sac and a yolk sac in it but no fetal pole yet. i have waited 2 weeks and have to wait 6 more days for my next us.
Second ultrasound at 8w 6d showed gestational sac, yolk sac, and fetal pole measuring 5 1/2 weeks, but no heartbeat.
I'm scheduled for a third ultrasound next wed, which would be 10weeks, and if there's no hb, it's over
Is this possible - to be almost 3 weeks behind? My dates can't be that far off!
Also, my doc did the 2 ultrasounds in the office, but gave me the option to have the 3rd at the hospital. Is there any benefit to that, vs having my doc do it?
maybe the fetal age & gestational age are what's causing the confusion.. I found this to maybe explain it? not sure..
"The fetal age is another term that refers to the actual age of the baby starting at the time of conception. So typically, fetal age is going to be two weeks less than gestational age."
I'd just ask my doctor to clarify though.. your due date that is.
It takes 6-12 days for the egg to implant after it is fertilized, and depending on when implantation took place, which is impossible to tell the baby may look bigger, and it's not uncommon for a baby to be measuring bigger. My doctor told me that even early ultrasounds can be off by up to 5 days to a week. I wouldn't worry about it right now. Are you estimating gestational age by the first day of your last menstrual period?
The baby only measured 1cm which from my research isnt as big as most are this far long however Im not panicking about that as Ive been told all fetal development is different. Ive also taken some comfort in how nauseated ive been which to me is a good sign, but not so fun! So as of now I am relaxed and excited!!
im also confused about
You should be able to find charts of estimated fetal weight by gestational age online. The charts should also show low and high weights for the gestational age also.
