What To Expect During Week 4 Of Pregnancy

Does Morning Sickness At 4 Weeks Pregnant Mean Twins

Pregnancy week 15 -What to expect?

The only definitive way to determine whether or not youre carrying twins is by ultrasound.

Women who are carrying twins or multiples, however, will have higher levels of hCG. We know that changes in the levels of hCG can be a cause of pregnancy-related sickness.

Therefore if youre experiencing nausea or vomiting from very early on, it could be an early sign that perhaps theres more than one growing baby in there.

Its impossible to guess just from what youre experiencing, though, as every woman will experience their pregnancies differently.

When Do Most Women Find Out They Have Miscarried

Statistics tell us that around 50% of pregnancies do end in miscarriages, but most of those women have no idea they were even pregnant in the first place. The majority of miscarriages happen in the first two weeks after conception, and the woman thinks she is just having a slightly heavier menstrual cycle than normal.

Pregnancy Symptoms Week 5

During week 5 of pregnancy, your hormones are running the show. Estrogen, progesterone, and hCG are elevated to keep your pregnancy on track. These hormones can cause many symptoms, and lots of women start feeling their effects during week 5 of pregnancy. Some of the most common symptoms of early pregnancy include:

  • Fatigue: this is one of the most common symptoms of early pregnancy. Most of your energy is going to your baby, so its normal to feel tired often.
  • Morning sickness: morning sickness can actually happen at any time of the day. Nausea and vomiting are more common during the first trimester, and they tend to subside later in your pregnancy.
  • Tender breasts: at 5 weeks pregnant, your breasts could feel sore and swollen.
  • Cravings: many women experience food cravings and aversions during their pregnancy.
  • Frequent urination: the hormones in your body increase the blood flow to your pelvic area and to your kidneys which means youll need to take more frequent trips to the bathroom.
  • Cramps: some mild uterine cramping is perfectly normal at this stage. It could be due to your uterus getting slightly larger or a sign of embryonic implantation.
  • Light spotting: dont be scared if you have light spotting on week 5 of pregnancy. This is another sign that the embryo has implanted inside your uterine lining. But if the spotting – or cramping – doesnt stop or gets worse, dont hesitate to call your doctor.

What Is Happening With Your Baby When You Are 4 Weeks Pregnant

There are three layers to your baby- the ectoderm, mesoderm, and endoderm. These three layers will form the babys organs and tissues. The ectoderm will become the nervous system , skin, hair, nails, mammary glands, sweat glands, and enamel for the teeth. The mesoderm will become the heart, circulatory system, skeleton, connective tissues, blood system, urogenital system, and the muscles. The endoderm will house the lungs and develops into the lining of the gastrointestinal tract, the liver, pancreas, and thyroid. Arm and leg buds begin developing at this point, although they are not clearly distinguishable. The placenta has also begun to form and is producing some important hormones including hCG. There is a movement of rudimentary blood through the main vessels.*

What Role Does Progesterone Play In Pregnancy

This all-important hormone kicks into gear shortly after ovulation by helping the uterine lining to become receptive to implantation of a fertilized egg. Progesterone, along with the hormone relaxin, can cause some GI woes, such as heartburn, indigestion, constipation, and bloating.

Progesterone teams up with relaxin again to help soften ligaments and cartilage, and loosen your joints to prepare you for labor. And if your gums swell and start to bleed, your skin breaks out or you feel super sweaty, thats the handiwork of this chemical, too.

What Role Does Oxytocin Play In Pregnancy

Though oxytocin is around throughout your pregnancy, this muscle-contracting hormone is mostly known for stimulating labor contractions. And if your labor is slow to progress, you might get a shot of Pitocin, the synthetic version of oxytocin, to help move things along. Once youve delivered, oxytocin helps to shrink the uterus down in size and move milk into the breasts.

What Is Implantation Bleeding

Implantation bleeding is light bleeding or spotting that occurs between seven and 14 days after fertilization.

After ovulation and at the moment an egg is successfully fertilized by a sperm in a fallopian tube, the embryo starts dividing and growing. At this time, the inner lining of the uterus, called the endometrium, starts to change. It’s already been thickening throughout the menstrual cycle, but itll need to grow and mature even more to protect and nourish an embryo.

Around five to six days after fertilization, the quickly growing embryo has moved down the fallopian tube and into the uterus. Its starting to need more nutrients, and the endometrium has filled in enough to support it.

Next, the embryo attaches itself to the endometrium, where it becomes reliant on a mothers body for the first time for nutrients and oxygen. When the embryo implants, it can disrupt tiny blood vessels in the spot it burrows into. This wont cause any problems but some women will experience light bleeding, from pinkish or red to brown discharge.

What Role Does Relaxin Play In Pregnancy

4 Weeks Pregnant – What to Expect Your 4th Week of Pregnancy

If you do end up conceiving, relaxin is at the ready and lives up to its name, since it helps to relax your muscles, bones, ligaments and joints in the pelvis later in pregnancy in preparation for labor. Relaxin also softens and lengthens the cervix. Its limbering mechanism may make you feel off balance and wobbly as you walk .

How Is Pregnancy Calculated

There can be a lot of confusion when discussing the way in which pregnancy is calculated.

What Role Does Estrogen Play In Pregnancy

Along with progesterone, estrogen is one of the two main hormones that get the pregnancy party started. Produced by the ovaries and later by the placenta, estrogen helps the uterus grow, maintains uterine lining, regulates other key hormones and triggers the development of babys organs. And when its time to breastfeed, estrogen promotes the growth of breast tissue and helps milk flow.

Got a stuffy nose or blotchy skin? Estrogen is also behind swollen mucous membranes and it causes extra blood flow to your skin, which can result in a red, itchy complexion. And estrogen joins other hormones to cause hyperpigmentation like darker nipples and melasma, brown patches on nose, cheeks and forehead.

Your Pregnancy, Week 4

Your baby at 5 weeks pregnant is actually looking a bit like a tadpole. The placenta, amniotic sac, and umbilical cord are still forming. Instead, the baby is surrounded by the gestational and yolk sacs, which also provide protection and nutrients to the 5-week old embryo.

Most of your babys systems are beginning to form during week 5 of pregnancy. This includes their nervous and circulatory systems.

Bleeding Gums And Dental Care

Say cheese and take a good look in the mirror. You might notice that you have red, swollen gums and they may even be sore, sensitive or prone to bleeding when you brush or floss. It’s those pregnancy hormones at work again, this time triggering gingivitis, an infection and inflammation of the gums, by making them react differently to the bacteria in plaque.

Those hormones are also the cause behind a chronic stuffy nose or even nosebleeds. Look even more closely and you may notice a small lump on your gums, called a pregnancy tumor. Before you start worrying, keep in mind that these benign growths are scarily named but completely harmless and painless. If you do develop one, it should go away on its own after delivery.

What is a little more alarming is what can happen if you don’t take care of your teeth while you’re expecting. Gingivitis can progress to an infection of the bones and tissues supporting your teeth called periodontitis and research has shown a link between periodontitis, premature labor and preeclampsia.

Prevention is key: Good oral hygiene, which includes regular dental care, brushing at least twice a day and gentle flossing once a day, will greatly reduce gum swelling, bleeding and soreness.

Th Week Pregnancy Symptoms

When women get a positive pregnancy indication, it is often in their 4 or more weeks of pregnancy. Therefore, you are most likely to miss your period, which is the major symptom. You may easily get a red streak in your pregnancy test kit by now. But make sure to take the test at the end of the week for better accuracy.

Tender breasts

This is usually one of the first signs of pregnancy and starts between 4 to 6 weeks and lasts till the end of the first trimester.

Your Babys Growth During Pregnancy Week 4

The 4th week of pregnancy is a week for implantation. The blastocyst finally sets itself up in the uterine lining and splits into two to form placenta and embryo. This is the week when the amniotic sac or the bag of water and the yolk sac, a part of your babys digestive system, forms around the little embryo. Your little embryo also grows into three distinct parts during the 4th week. These three parts of the embryo, endoderm , mesoderm and ectoderm , later form your babys body organs. No doubt, its an important week for the growth and development of your little wonder.

Mom’s Body At 4 Weeks Pregnant

4 Weeks Pregnant

This week, a few pregnancy symptoms may appear, though some moms-to-be won’t have noticed any signs yet. You might feel some cramping and see a little bit of spotting, both of which can happen as the fertilized egg implants itself in your uterus.

Your body is now starting to make the pregnancy hormone hCG. This hormone tells your ovaries to stop releasing an egg each month, thus stopping your monthly period, and it also increases the production of other hormones, such as estrogen and progesterone. If you’ve taken a home pregnancy test and gotten a positive result, that’s because these tests are designed to detect levels of hCG in your urine.

The First Trimester: What To Expect

A healthy first trimester is crucial to the normal development of the fetus. You may not be showing much on the outside yet, but on the inside, all of the major body organs and systems of the fetus are forming.

As the embryo implants itself into the uterine wall, several developments take place, including the formation of the:

  • Amniotic sac. A sac filled with amniotic fluid, called the amniotic sac, surrounds the fetus throughout the pregnancy. The amniotic fluid is liquid made by the fetus and the amnion that protects the fetus from injury. It also helps to regulate the temperature of the fetus.

  • Placenta. The placenta is an organ shaped like a flat cake that only grows during pregnancy. It attaches to the uterine wall with tiny projections called villi. Fetal blood vessels grow from the umbilical cord into these villi, exchanging nourishment and waste products with your blood. The fetal blood vessels are separated from your blood supply by a thin membrane.

  • Umbilical cord. The umbilical cord is a ropelike cord connecting the fetus to the placenta. The umbilical cord contains two arteries and a vein, which carry oxygen and nutrients to the fetus and waste products away from the fetus.

It is during this first trimester that the fetus is most susceptible to damage from substances, like alcohol, drugs and certain medicines, and illnesses, like rubella .

During the first trimester, your body and your babyâs body are changing rapidly.
