The most critical period of its development is between three and seven weeks after fertilization, when a simple heart tube assumes the shape of a four-chambered heart. In fact, the heart actually begins beating by the 22nd day of life.
When you are 5 weeks pregnant, your baby's heart is made up of two tiny channels called heart tubes and they're already hard at work, beating to their own drummer (it will be weeks before those beats become coordinated).
Hi, I'm 6 weeks pregnant at the moment and i thought everything was going find until i got a call from my hospital telling me they needed to schedule me for an earlier appointment because when reviewing my ultrasounds they saw a problem with the fetus development. does anyone have any idea what this can mean? I would really appreciate it if you can help.
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.
If you break embryonic and fetal development into thirds then when you are in your 28th week the baby begins its final third of development. (Gestation is 266 days or 38 weeks of development). So either way you look at it you are in your 3rd trimester!
I'm 22 weeks, this is my 4th pregnancy...2nd baby to make it past 8 weeks. Doctors where I live don't recommend u/s before 10 weeks to detect heartbeat because they are not accurate enough.good luck...
Sorry to hear this. I had never heard of this and did some research. This is what I found. Hope it helps and prayers for you && the little one :)
CPCs can form within this structure and come from fluid trapped within this spongy layer of cells, much like a soap bubble or a blister. CPCs are often called "soft signs" or fetal ultrasound "markers" because some studies have found a weak association between CPCs and fetal chromosome abnormalities.
they dont want the baby to be to big...and the ultrasound most people have to check the fetal size is a fetal size and development ultrasound to see how your baby is developing and so im pretty sure that if they were concerd about the development and baby not being fully developed they wouldnt change the due date.
