"Congratulations! A live fetus!" The zygote migrates from tube into the fundal uterus with implantation on day 22–25.
The first ultrasound sign of pregnancy is a gestational sac (chorionic sac-5th week) that appears as a double ring that is comprised of the certain membranes and confirm that it is implanted just below the surface of endometrium. Also the uternie orientation and consistency are also evaluated to see the sustenance of pregnancy.
So you are both saying that it couldnt be his? One of my professors said that a zygote can float around 2-3 weeks before implantation. I'd be really, really relieved and happy if I could rule out it being his and know it's mine and maybe just developed fast. Especially if I can do so without having to spend $1000+ on a ambiotic paternity test.
is important to fetal lung development. The fetus gets all of its oxygen and nutrients through the placenta and umbilical cord---a process called fetal circulation.

Despite the deep unpopularity of fetal personhood bills in 2012, Rep. Paul Ryan (R-Wis.) has again decided to cosponsor the Sanctity of Human Life Act, a bill that gives full legal rights to human zygotes from the moment of fertilization.
Ryan, who reportedly has 2016 presidential ambitions, had to de-emphasize his opposition to abortion without exceptions during the 2012 election to align his position with presidential candidate Mitt Romney.
But more importantly, once she does become pregnant, low thyroid hormones will definitely impact the developing fetus. The earliest stages of fetal development is the time when it is most critical for the mother to have sufficient thyroid hormone.

The brain contains pockets or spaces called ventricles with a spongy layer of cells and blood vessels called the choroid plexus. This is in the middle of the fetal brain. The choroid plexus has the important function of producing a fluid called cerebrospinal fluid. The fluid produced by the cells of the choroid plexus fills the ventricles and then flows around the brain and the spinal cord to provide a cushion of fluid around these structures.

I personally think it's selfish and foolish to drink during pregnancy. Your putting your baby's health at risk and fetal development during the first trimester is crucial. Any alcohol use during pregnancy can result in a child being born with FASD. To me it's not worth the risks.
The fetal heart undergoes a considerable amount of growth very early in pregnancy. 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.
Puberty occurs in two separate stages, genital (penis and testicle) development and pubic hair development. We number each of these stages 1-5, 1 being child and 5 being adult. That means 2-3-4 are the stages of puberty. Depending on your development, a number is assigned to genital development (G) and a number is assigned to pubic hair development (P).
For example, if you have just started growing hair you might be stage P2. It's possible to be P2 and still be G1.
Your Baby is still in the early stages of fetal development, & his or her bones/muscles are not strong enough to be noticeable quite yet. I thought maybe i had felt some around this time to but, turns out it was my own heart beating in my belly due to extra blood flow. I hate to sound discouraging :(
You will however feel them between 18-20 weeks if you are a first time mom so, you really don't have to wait much longer!! The feeling is unmistakable :) hope this helps, goodluck!
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.
They do not have any long term studies to show the effects on fetal development. My current dr says the same thing, when pg stay clear of it as possible.
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!
I quit smoking cigarettes and weed the minute I found out but I am concerned about fetal development since I found out after the fact. Thanks again for your insight.
