  • What to Expect During Each Trimester of Pregnancy
  • Pregnancy is an exciting time when your body goes through many changes. Your growing baby also goes through a rapid series of changes as they grow from a cluster of cells into the baby that you get to welcome into the world.

    The average pregnancy lasts about 40 weeks, although it is normal to deliver with the range of 2 weeks before or after this date. These weeks are also broken up into trimesters that all include a specific set of symptoms and stages of development. Learning more about the stages of pregnancy month-by-month helps you to know how to take care of yourself and your baby for a healthy delivery.

    What To Expect During The Third Trimester

    The third trimester marks the home stretch, as you get ready for the birth of your baby. The fetus continues to grow in weight and size, and the body systems finish maturing. You may feel more uncomfortable now. You will continue to gain weight and begin to have false labor contractions .

    During the third trimester, it’s a good idea to start taking childbirth classes to get ready for the big day. This is especially true if this is your first pregnancy. Breastfeeding is best for your baby. Talk with your healthcare provider about the benefits of breast milk.

    During the third trimester, both your body and the fetus continue to grow and change.

    What Factors Determine The Outcome Of You And Your Baby’s Health

    Many events determine the outcome of a pregnancy.

    Maternal weight gain: The amount of weight a woman gains when pregnant can be important in predicting the outcome of pregnancy. Excess weight gain places a woman who is pregnat at risk for diabetes and hypertension, and it may increase the chance for needing a cesarean birth . Too little weight gain places the infant at risk for interuterine growth restriction and the mother at risk for anemia, nutritional deficiencies, and osteoporosis.

    Nausea and vomiting: Even if a pregnant patient experiences what seems like an abnormal amount of nausea and vomiting , it probably will not affect the baby’s health, particularly if the woman is still gaining weight at the anticipated rate.

    Low or high red blood cell counts: The normal red blood cell count range varies slightly between laboratories, but is generally 4.2 – 5.9 million red cells per microliter. The risk of delivering prematurely is increased if the woman’s blood count is low . Low blood counts also put her at risk of requiring a transfusion following a delivery. If the woman’s blood count is too high , her baby may be larger than expected.

    Maternal obesity: A person with a body mass index over 30 is considered obese. If a woman who is pregnant is obese and has diabetes, her baby is three times more likely to have a birth defect. If she is obese but does not have diabetes, the risk of birth defects is not increased.

    How Is Your Due Date Calculated

    At one month pregnant, youâll be eager to know when your newborn will arrive. Our Due Date Calculator can give you an estimate, but your healthcare provider may be able to give you a more accurate date. Your due date is calculated as 40 weeks, or 280 days, from the first day of your last menstrual period. Keep in mind that your due date is just an estimate. You may not remember the date of your last period the length of your menstrual cycle may be shorter or longer than the 28-day average and itâs very difficult to know exactly when ovulation or fertilization occurred. Keep in mind, only a small percentage of babies are born exactly on their due date and most babies are born in the two weeks either side of their due date.

    What Tests Confirm That You Are Pregnant

    Pregnancy Stages: Trimesters

    Several tests may be conducted while a woman is pregnant.

    Pregnancy tests

    The woman’s urine or blood may be tested.

    Women may choose to perform a home pregnancy test. This is a urine test kit that can be purchased at a pharmacy or grocery store without a prescription. The test can indicate whether a woman is pregnant. This type of test is known as a qualitative test. It can only test for the presence of the pregnancy hormone, beta-hCG. If a doctor is considering prescribing a medication that might not be appropriate for consumption during pregnancy, one of these simple tests may be performed in the office to determine if a woman is pregnant or to make sure she is not pregnant. If the test is performed very early in a pregnancy, the hormone level may still be negative. Most current home pregnancy tests can show positive results immediately after the first missed menstrual period.

    If your OB/GYN or Midwife may order sophisticated tests are called quantitative hCG levels. These testes determine the hCG levels in the bloodstream. This type of test is done by drawing blood for testing. These levels indicate approximately how far along a woman is in her pregnancy. If levels of hCG do not rise as she progresses through her pregnancy, it could indicate a problem pregnancy such as an ectopic pregnancy with low levels or twins with high levels.


    A doctor may use sound waves to examine the pelvic structures such as the uterus, ovaries, and the embryo or fetus.

    When Does A Pregnancy Start

    The start of pregnancy is actually the first day of your last menstrual period. This is called the gestational age, or menstrual age. Its about two weeks ahead of when conception actually occurs. Though it may seem strange, the date of the first day of your last period will be an important date when determining your babys due date. Your healthcare provider will ask you about this date and will use it to figure out how far along you are in your pregnancy.

    Fetal Development During The Third Trimester

    During the third trimester, the fetus continues to grow in size and weight. The lungs are still maturing. The fetus starts to position itself head-down. By the end of the third trimester, the fetus is about 19 to 21 inches long and weighs about 6 to 9 pounds. Fetal development during the third trimester includes:

    • The fetus can see and hear.

    • The brain continues to develop.

    • The kidneys and lungs continue to mature.

    • The bones of the skull stay soft to make it easier to pass through the birth canal.

    • For many babies, the irises of the eyes are slate blue. The permanent eye color will not appear until several days or weeks after birth.

    • The fetus can suck its thumb and can cry.

    • The baby is covered in vernix caseosa . This is a creamy, protective coating on the skin.

    • The head will often turn downward during the last couple of weeks of pregnancy.

    What Is Morning Sickness

    Morning sickness consists of nausea and vomiting. It is caused by pregnancy hormones. Many pregnant people have it to some degree in their first trimester. Despite what it sounds, morning sickness can occur at any time of day. Certain foods or smells might make you feel sick and sometimes vomit. Some people seem to feel sicker when their stomachs are empty. Morning sickness usually goes away by the second trimester.

    There are over-the-counter vitamins and herbal supplements that may help with morning sickness. Taking vitamin B6 may help with nausea, even though it may not prevent vomiting. Ginger supplements also may relieve nausea.

    How Is Your Baby Developing This Month

    The Pregnancy | Month by month | English | Month 3 | Dr Padma

    After conception, the fertilized egg travels along the fallopian tube to the uterus, where it will implant in the uterine lining. The egg divides into a bunch of cells, some of which become the embryo and some of which eventually become the placenta, which will provide nourishment for your baby during your pregnancy. The umbilical cord also forms between the embryo and the placenta, delivering nutrients and removing waste. The upcoming month is a time of rapid growth for your little one, as internal organs, bones, and tiny limbs are beginning to form.One quick note on the terminology you might see when reading up on baby development: During the first eight weeks, your little one may be referred to as an embryo in medica circles, whereas after this point your baby may be called a fetus until she is born.

    What’s Happening Inside You

    The fertilized egg grows, and a water-tight sac forms around it, gradually filling with fluid. This is called the amniotic sac, and it helps cushion the growing embryo.

    The placenta also develops. It is a round, flat organ that transfers nutrients from you to the baby and transfers the babys wastes.

    A primitive face takes form with large dark circles for eyes. The mouth, lower jaw, and throat are developing. Blood cells are taking shape, and circulation will begin.

    The Second Trimester: What To Expect

    Pin on Health &  Fitness

    The second trimester marks a turning point for the mother and fetus. You will usually begin to feel better and start showing the pregnancy more. Your fetus has now developed all its organs and systems and will now begin growing in length and weight.

    During the second trimester, the umbilical cord continues to thicken as it carries nourishment to the fetus. However, harmful substances also pass through the umbilical cord to the fetus, so care should be taken to avoid alcohol, tobacco and other known hazards.

    During the second trimester, both your body and the fetus continue to grow.

    What Happens In Each Of The Phases Of A Pregnancy

    Human pregnancy normally lasts between 38 and 40 weeks after fertilization. This is, as we well know, about nine months. And although at the biological level the fetus does not go through clearly differentiated stages, at the clinical level it is useful to divide the pregnancy into stages. And these phases are the famous quarters. Each trimester is made up of three months and, as a rule, each of them is linked to certain complications. Hence the importance of dividing the pregnancy into these three stages.

You may not need as many naps, your morning sickness seems to fade away, and you may feel a spring in your step. You may feel these positive changes because the worry of early miscarriage is over, or because your hormones are a bit less volatile as the placenta has taken over the production of some hormones to sustain the pregnancy. Your sex drive is usually back to prepregnancy levels.

    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 Happens Right After Conception

    Stages of pregnancy month by month

    Within 24 hours after fertilization, the egg begins rapidly dividing into many cells. It remains in the fallopian tube for about three days after conception. Then the fertilized egg continues to divide as it passes slowly through the fallopian tube to the uterus. Once there, its next job is to attach to the endometrium. This is called implantation.

    Before implantation though, the blastocyte breaks out of its protective covering. When the blastocyte makes contact with the endometrium, the two exchange hormones to help the blastocyte attach. Some women notice spotting during the one or two days when implantation happens. This is normal and isnt something you should worry about. At this point, the endometrium becomes thicker and the cervix is sealed by a plug of mucus.

    Within three weeks, the blastocyte cells ultimately form a little ball, or an embryo. By this time, the babys first nerve cells have formed.

    Your developing baby has already gone through a few name changes in the first few weeks of pregnancy. Generally, your baby will be called an embryo from conception until the eighth week of development. After the eighth week, the baby will be called a fetus until its born.

Pregnancy seems like it will last forever, and now you realize that its almost time for your baby to arrive.

    How Early Can I Know Im Pregnant

    From the moment of conception, the hormone human chorionic gonadotrophin will be present in your blood. This hormone is created by the cells that form the placenta . Its also the hormone detected in a pregnancy test. Even though this hormone is there from the beginning, it takes time for it to build within your body. It typically takes three to four weeks from the first day of your last period for the hCG to increase enough to be detected by pregnancy tests.
