If a possible complication in early pregnancy is suspected, your health care provider will use a combination of blood tests and ultrasound tests to make a clear diagnosis. It is common to have many questions about what this early development truly involves and what is to be expected. This information should be used as a general guide for healthy pregnancy development, although development may vary due to the mother’s health or a miscalculation of ovulation.
Most references to pregnancy are usually in gestational age rather than fetal age development, but we have included both so that it is clear what stage development is being discussed. At this stage, the menstrual period has just ended and your body is getting ready for ovulation. When conception takes place, the sperm will penetrate an egg and create a single set of 46 chromosomes called a zygote – the basis for a new human being. The earliest change that can be seen through a vaginal ultrasound at this time will be the “decidual reaction,” which is the thickening of the endometrium. A key fact to remember when choosing an ultrasound is that a transvaginal ultrasound can detect development in the uterus about a week earlier than a transabdominal ultrasound.
Once implantation occurs, the pregnancy hormone Human Chorionic Gonadotropin (hCG) will develop and begin to rise.
Doctors will often use the quantitative test if they are closely monitoring the development of a pregnancy. When the egg is fertilized, the corpus luteum will continue to produce progesterone for the developing pregnancy until the placenta takes over around week 10. Sometimes, the failure of the corpus luteum to adequately support the pregnancy with progesterone can result in an early pregnancy loss. Around 5 weeks, the gestational sac is often the first thing that most transvaginal ultrasounds can detect. With both hCG levels and progesterone levels, it is not the single value that can predict a healthy pregnancy outcome.
Between 5 ? to 6 ? weeks, a fetal pole or even a fetal heartbeat may be detected by vaginal ultrasound.
The fetal pole now allows for crown to rump measurements (CRL) to be taken, so that pregnancy dating can be a bit more accurate.
If a vaginal ultrasound is done and no fetal pole or cardiac activity is seen, another ultrasound scan should be done in 3-7 days. Generally from 6 ? -7 weeks is the time when a heartbeat can be detected and viability can be assessed. Once a heartbeat is detected, the chance of the pregnancy continuing ranges from 70-90% dependent on what type of ultrasound is used.
If your doctor is concerned about miscarriage, blighted ovum, or ectopic pregnancy, the gestational sac and fetal pole (if visible) will be measured to determine what type of development should be seen. If the fetal pole is too small to take an accurate measurement, then a repeat scan should be done in 3-5 days. By this point in the pregnancy, everything that is present in an adult human is present in the developing embryo.
If a strong heartbeat is not detected at this point, another ultrasound scan may be done to verify the viability of the fetus.
The hCG levels will peak at about 8-12 weeks of pregnancy and then will decline, remaining at lower levels throughout the remainder of the pregnancy.

During week 13 of pregnancy, your baby’s body is now beginning to catch up in size with the head, which currently makes up about a third of his or her body size. If you had been suffering from morning sickness, you will be relieved to know that most expectant mothers start to feel better by week 13 of pregnancy.

As you read through the information on what happens to your body and your baby throughout your pregnancy (week by week), also listen to your own body. Look through the pictures below to see what baby development looks like in the early weeks – please note that some of the below pictures are actual photographs of human babies. All photographs are pictures taken by doctors after assisting families who lost their babies to miscarriage or ectopic pregnancy.
We have gathered information from different sources in order to provide the best guidelines of what normal early fetal development looks like. Gestational age is the age of the pregnancy from the last normal menstrual period (LMP), and fetal age is the actual age of the growing baby. For most women, ovulation takes place about 11 – 21 days from the first day of the last menstrual period.
Anywhere from day 6 – 12 after conception, the blastocyst will imbed into the uterine lining and begin the embryonic stage.
After implantation occurs, the hormone will begin to rise and should increase every 48-72 hours for the next several weeks.
It will release progesterone that helps thicken and prepare the uterine lining for implantation. Progesterone inhibits immune responses, decreases prostaglandins, and prevents the onset of uterine contractions. Although development may be seen earlier, these levels provide a guide of when something is expected to be seen. It is more important to evaluate two different values to see if the numbers are increasing. In situations when there is a concern of an ectopic pregnancy or miscarriage, hCG levels will often start out normal, but will not show a significant increase or will stop rising all together, and progesterone levels will be low from the beginning. The fetal pole may be seen at a crown-rump length (CRL) of 2-4mm, and the heartbeat may be seen as a regular flutter when the CRL has reached 5mm. Due to the fact that pregnancy dating can be wrong, it would be much too early at this point to make a clear diagnosis on the outcome of the pregnancy. If the embryo is less than 5mm CRL, it is possible for it to be healthy without showing a heartbeat, though a follow up scan in 5-7 days should show cardiac activity.
If there is absence of a fetal pole, then further testing should be done to rule out the possibility of an ectopic pregnancy.
About 50% of women do not undergo a D&C procedure when an early pregnancy loss has occurred. If the levels are questionable, an ultrasound scan should be used to diagnose the pregnancy outcome. Your tax deductible contribution provides valuable education and more importantly support to women when they need it most.
Your baby is now the size of a peach, measuring about three (3) inches in length from crown to rump and weighing just about one (1) ounce. The fingerprints begin to form on the touch pads on the fingertips during week 13 of pregnancy. However, if your stomach is still turning, take comfort in knowing that your nausea should subside within the next week or two.


If, however, you are still feeling hands off, your lack of libido is completely normal two. My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.
Ultrasounds can be used to visually see what development is taking place in the uterus and to measure the progress. This cannot always be detected by ultrasound—sometimes it may take a special eye or very good equipment to see this “reaction” in the endometrium lining. Once the levels have reached at least 2,000, some type of development is expected to be seen in the uterus using high resolution vaginal ultrasound. This pole structure actually has some curve to it with the embryo’s head at one end and what looks like a tail at the other end.
A strong fetal heartbeat should be detectable by ultrasound, with a heartbeat of 140-170 bpm by the 9th week. Ultrasound findings are much more accurate at diagnosing pregnancy viability after 5-6 weeks gestation than hCG levels are.

The intestines continue to move from inside the umbilical cord to neatly fold in place inside the abdomen. Your baby continues to open and close his or her little hands into fists and to curl his or her little toes. During week 13 of pregnancy, you may also notice that you are feeling more hungry than usual.
Pregnancy is the perfect chance to grow your awareness of yourself as you bond with your baby.
Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them. Some of the bones in your baby’s tiny body are also beginning to harden, specifically the bones in the arms and legs. Just keep in mind that you need only about 300 extra calories per day while pregnant; gaining too much weight too quickly can be dangerous to you and to your baby.
This white or yellowish discharge protects your baby by keeping harmful germs washed out of the vagina.
If your baby is a girl, her ovaries now contain the approximately two million eggs that she will have for life.
Your baby continues to suck in and swallow amniotic fluid and has also begun to suck on his or her thumbs. Talk to him or her, relax, and spend this week of pregnancy enjoying yourself and your changing body. The external genitalia also continue to develop, although you will not be able to determine the sex of your baby visually for another few weeks. You may also begin leaking colostrum, which will be baby’s first food before your breasts produce mature breast milk around three to five days postpartum.
Many women, however, never leak during pregnancy and go on to successfully breastfeed their babies.
You may also now be sporting an obvious baby bump, which is more the result of your enlarged uterus, which has grown out of the pelvis and into the abdomen, than of your peach-sized baby. Other symptoms during week 13 of pregnancy include lessening fatigue, food cravings and aversions, heartburn and indigestion, constipation, and dizziness.
