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).
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!!
It could mean anything. It could mean that it's not developing as it should according to your dates, or it could be more developed than your dates. They're being very vague and unfortunately there is not much else you or we can do or tell you until you get that ultrasound and see what's going on. I know how horrible the wait can be from my own experience but just try be positive.
( It affects the brain and spine/nervous system so I'm assuming it could range greatly in severity from minor brain development issues to spina bifida. I'm praying for you. :( Didn't your doctor give you any information on it? It's HORRIBLE that they left you with all these questions... I'm so sorry.
Lingual thyroid is a defect in fetal development that leaves thyroid tissue (often your only thyroid tissue) at the base of your tongue. At some point in the first month after conception, the tissue is supposed to drop down to the base of the neck. That's the normal location for the thyroid gland. If the thyroid doesn't descend (about 1 in 100,000 cases), it's trapped in a space where it can't function completely normally and doesn't produce enough thyroid hormone.
and with how much issues I have been having with my cervix I will most likely go into labor that week. I pray I make it to at least 37 weeks as I am concerned about his fetal brain and lung development, but I know that everything will happen in Gods timing.
Has anyone had a + marker for neural tube defect? I got my news earlier today that I have a 1% chance and I'm freaking out...
Hi!
Yes, that is too early to see a fetal pole or cardiac activity. In ten days, you should see a nice change with development of a little "grain of rice" with a tiny flickering heart beat. I wish you the best!
At that stage you will see a sac, yolk sac, and a teensy fetal pole and heartbeat via ultrasound. They do them trans vaginally at my office at that stage.
I hope it goes well for you! I would be very nervous as well. I miscarried my first baby, and an empty ultrasound screen can be heartbreaking.
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!
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.
There is no safe amount of alcohol you can drink. Fetal brain development damage can occur with just one drink.
It's included in my prenatal vitamins so I'll be taking it the entire time. It's super important in the beginning but won't hurt if you keep taking it the whole time. It helps with neural tube/brain development and baby's brain keeps growing a lot even later in pregnancy so it won't be bad for you you can stop after 12 weeks if you want.
