What Are The Signs Of Pregnancy
For a lot of people, the first sign of pregnancy is a missed period. Most pregnancy tests will be positive by the time youve missed your period. Other early pregnancy symptoms include feeling tired, feeling bloated, peeing more than usual, mood swings, nausea, and tender or swollen breasts. Not everyone has all of these symptoms, but its common to have at least 1 of them.
The First Trimester: Changes To Your Body
During pregnancy, many changes will happen to your body to help nourish and protect your baby. Women experience these changes differently. Some symptoms of pregnancy continue for several weeks or months. Others are only experienced for a short time. Some women experience many symptoms, and other women experience only a few or none at all. The following is a list of changes and symptoms that may happen during the first trimester:
Symptoms To Have Checked Out
With all of the changes going on in your body during pregnancy, you may wonder whats normal and whats not. In many cases, that odd twinge is not a cause for concern. However its also important to understand that your risk for miscarriage is the highest during the first trimester. Here are a few symptoms that do always warrant a call to your doctor:
- Fever over 101.5 F, chills and/or backache
- Severe puffiness in the hands/face
- Vision disturbances
If you experience any of the above symptoms, call your doctors office right away. If you dont get someone on the phone within a few minutes, head to the nearest ER.

How Do These First Trimester Changes Affect You
While women do not physically feel the egg and sperm meet, they may feel the egg implanting in the uterus. Some women report feeling a small cramp and a bit of spotting. This spotting is typically associated with the upcoming menstrual cycle when it is actually implantation spotting.
So, the hormones estrogen, progesterone and hCG are flooding the body at this point. From the first moments after conception, the body kicks into a gestational mode. These hormones are to blame for many of the pregnancy-induced symptoms women feel in the first trimester of pregnancy including nausea, vomiting, and fatigue. Some women actually feel like they have a touch of the flu for most of the first trimester of pregnancy. Hormones are not selective. They cannot increase in the bloodstream and selectively attend to only the needs of the fertilized egg . When progesterone levels rise, you will feel symptoms more.

Babys Growth In The First Trimester
During the first 13 weeks, your baby changes from a fertilized egg into a fully-formed fetus. All the major organs and systems are taking shape. That means your baby could be harmed if you use street drugs, have an illness, or get exposed to radiation. Heres whats happening:
The fertilized egg becomes a cluster of rapidly dividing cells that implants in your uterus. The placenta, umbilical cord and amniotic sac all start to grow.
Your babys nervous system changes from an open neural tube to a brain and spinal cord. Nerves and muscles start working together. Your baby can move on its own, but its too soon for you to feel it.
The heart takes shape and begins to beat. You can hear it on ultrasound as early as week 6. It beats 120 to 160 times per minute. Red blood cells are forming.
Your baby develops a digestive system, including intestines and kidneys.
They have lungs and other major organs, but theyre not fully developed.
A soft skeleton is starting to grow.
Your baby starts to look like a baby, with arms, legs, fingers, and toes. Their face gets eyes, ears, a nose, and mouth. A tongue and tooth buds grow. Eyelids cover your babys eyes, and by the end of the trimester, they even have fingernails.
Genitals start to grow, but its too early to tell by ultrasound whether youre having a girl or a boy.
Where You Want To Give Birth
You may want to start to consider where you would like to deliver your baby when its time to give birth. Women can choose to deliver at a hospital, birth center, or at their own home. You should weigh the pros and cons of each location and discuss them with your doctor.
The American Congress of Obstetricians and Gynecologists believes that hospitals and birthing centers are the safest place to deliver a baby. If there is an emergency, a hospital is fully equipped to handle the situation.

During the first 8 weeks of pregnancy, a rudimentary brain and spine form, along with muscles of the eyes, nose, and mouth. The fetus measures 11.5 inches , or 2.53.8 centimeters , at 8 weeks.
of the first trimester, all major organ systems have formed, although the organs are not fully developed.
Muscles and bones are beginning to form, and the external genitals are growing. An ultrasound cannot detect the sex of the fetus at this early stage, but a blood test may.
The fetus is larger at the end of the first trimester about 34 in long. Although the fetus starts moving in the first trimester, it is usually too small for the pregnant person to detect any movement.
However, some pregnant people report feeling movement very early, especially if they have been pregnant before.
The first trimester is the most vulnerable time for fetal development because all of the major organs are forming at this time.
The risk of pregnancy loss drops significantly in the second trimester.

What Happens During Week 3
The fertilized egg moves down your fallopian tube and divides into more and more cells. It reaches your uterus about 34 days after fertilization. The dividing cells then form a ball that floats around in the uterus for about 23 days.
Pregnancy begins when the ball of cells attaches to the lining of your uterus. This is called implantation. It usually starts about 6 days after fertilization and takes about 34 days to be complete.
Pregnancy doesnt always happen, even if an egg is fertilized by a sperm. Up to half of all fertilized eggs pass out of your body when you get your period, before implantation is complete.
What Can Be Expected From The Doctor And Midwife
Your antenatal health checks might be with your GP, a midwife or an obstetrician, depending on where you will give birth. During your first antenatal health check, you will probably have your pregnancy confirmed with a urine or blood test. These are more reliable than home pregnancy tests. First trimester antenatal health checks usually happen every 4 to 6 weeks, but this can vary, based on your health and how your baby develops.
Many women are offered an ultrasound scan at around 12 weeks you might hear the babys heartbeat at this scan. This ultrasound will also show if you are having a multiple birth and can help estimate the babys size and due date, as well as check for some health conditions.
Other health checks during the first trimester include:
- urine tests to detect urinary infections, a common but manageable condition that if left untreated can trigger pre-term labour
- blood tests to check your blood type , iron levels, blood sugars , rubella immunity, and other infections such as HIV, hepatitis B and syphilis
- general maternal health and wellbeing checks, including a discussion of concerns you might have about your pregnancy or general health, and a medication review to check for safety during pregnancy
