Pregnancy Symptoms First Couple Weeks

Wondering if you’re pregnant? Even if it’s still early days, there are tell-tale signs that your body is changing. Early symptoms of pregnancy may include:

  • a missed period
  • tender breasts
  • feeling nauseous
  • increased vaginal discharge
  • tiredness



Some, but not all, women get the feeling that they’re pregnant a few days after they’ve conceived. So it’s possible that you may experience pregnancy symptoms as early as two weeks after conception.

It may be two weeks since you conceived, but your doctor will calculate that you’re four weeks pregnant. She’ll count your pregnancy from the first day of your last period. There’s no way of knowing for sure the exact date that the embryo implanted in your womb (uterus), which is when you conceived.

Every pregnancy is different, so it’s hard to predict if you’ll notice changes in your body, especially just two weeks after conception.

Early pregnancy symptoms, such as tender breasts, tiredness and feeling sick, are easy to confuse with signs that your period is coming on. For most women, the first sign they notice is a missed period.



You may feel a prickling or tingling sensation in your breasts, particularly around your nipples. It happens because pregnancy hormones increase the blood supply to your breasts.

This can be one of the earliest signs of pregnancy. You may notice how tender your breasts feel within a week or so of conception. Your usual bra may become uncomfortable, and feel more chafing than usual. However, sore breasts more commonly become noticeable about three weeks to four weeks after conception.

Another early sign of pregnancy is the change in colour of your vulva and vagina. Your vulva and vagina are usually pink, but this changes to dark purplish-red as your pregnancy progresses.

The change is caused by the increased amount of blood being supplied to the tissues around your vagina. Midwives call this change in colour Chadwick’s sign.

It’s possible that if you’re particularly in tune with your usual menstrual cycle, you will notice changes to your vaginal discharge at this early stage.

It’s common to have more vaginal discharge in pregnancy. It’s usually harmless, and not that different from the discharge that you had before you were pregnant. The amount of discharge increases to discourage infections from travelling up your vagina. Don’t rinse out your vagina (douching), as this may irritate your skin and upset the natural, healthy balance of bacteria.

Pregnancy also makes you more likely to get thrush. Although this isn’t harmful to your baby, you’ll need treatment. If your vaginal discharge changes in appearance and smell, see your doctor.



During the first week of pregnancy, morning basal body temperature — your body temperature when you are completely at rest — will remain elevated. If you are noticing these changes, Pregnancy Corner recommends contacting your health care provider to set an appointment to test for the pregnancy. [Related: When and How to Take a Pregnancy Test]

Although there are few physical changes at this point, you may be noticing internal changes. Digestive issues — like gas, constipation and nausea — may be cropping up. You also may be noticing more fatigue than usual, and mood swings with the changing hormones. Tender breasts and morning sickness may also begin during the first week, though most women won’t notice those changes until after the second week of pregnancy.



Out of the 46 chromosomes, the two most important are the X chromosome and the Y chromosome. These two chromosomes determine the baby’s sex. Every egg has an X chromosome; every sperm has either an X or a Y chromosome.

If the sperm fertilizes the egg with an X chromosome, you’ll have a girl. If it’s a Y chromosome, you’ll have a boy. The gender is decided at the moment of fertilization, but you won’t know until weeks later.

The baby, which at this stage is called an embryo, consists of 150 cells that will begin to divide up into three separate layers. Here’s a brief breakdown of each layer and what it eventually transforms into:

1st Layer: The internal layer, and also known as the endoderm or endoblast, becomes the digestive system and respiratory tract, which includes glands like the pancreas, thyroid, liver and thymus.

2nd Layer: The middle layer, and also known as the mesoderm, becomes the baby’s bones, cartilage, circulatory system, inner skin layer, muscles, genitalia, excretory system, and outer covering.

3rd Layer: The outer layer, and also known as the ectoderm or ectoblast, becomes the nervous system, the brain, and the epidermis, which includes the baby’s skin, nails, and hair.

During this time of transformation, the embryo simply floats within the uterus, protected by the secretions of the uterus lining. The baby is still very, very small — only .1 to .2 mm long.



First and foremost, say goodbye to your menstrual period for the next nine months; you will not have another one until after the baby is born (but if you think you’re getting off easy, think again). Also, the uterus is increasing its production of endometrium, which provides a healthy environment for the baby to implant.



The most important thing a woman can do during this stage is to change any negative habits she may have. Quitting bad habits (such as smoking, drinking, and drugs) is important to a healthy pregnancy, a healthy birth, and a healthy baby.

Hopefully, if this is a planned pregnancy, you’ve already dropped some of these habits (or never had them) and begun taking prenatal vitamins, as well as increased doses of folic acid. You should ask your obstetrician which habits are okay to retain during your pregnancy.



Pregnancy begins when a fertilized egg implants in the uterus.

Women may experience a wide range of common symptoms during pregnancy.

Foetuses grow and change dramatically throughout a pregnancy.

Women go through many changes during each stage of pregnancy. Many of the pregnancy symptoms they have and the changes they deal with are common to all healthy pregnancies. The stages of embryonic and foetal development also follow a common pattern.

Still, pregnancy can be confusing and sometimes mysterious. It’s normal to wonder what happens during each of the stages of pregnancy.

Whether you are pregnant, are a concerned partner or friend, or are just curious, you may have many questions. Here is a description of the stages of pregnancy and the changes that women go through during a healthy pregnancy.



During conception, a sperm penetrates an egg and forms a zygote, a single set of 46 chromosomes — 23 from the male and 23 from the female. Chromosomes determine the baby’s sex and features. This is the beginning of the foetus. Over the first couple of weeks, the zygote travels through the fallopian tube toward the uterus. In the first round of cell division called cleavage, a ball of cells, called a morula, is formed. A cavity forms within the morula, and it now becomes a blastocyst. This blastocyst is made up of two parts — what will become the placenta and the embryo — and eventually ends up in the uterus. Between the first and second week of conception, the blastocyst attaches into the uterine lining, thus beginning the embryonic stage.


After these first weeks of foetal development, basic growth begins, as the brain, spinal cord, heart and gastrointestinal tract begin to form.



In the earliest stages of pregnancy, prenatal vitamins and minerals are very important. Folic acid should be added to the diet. About 400 micrograms a day will help the foetus develop a healthy brain and spinal cord. It’s also a good idea to give up alcohol and stop smoking cigarettes. Though a glass of wine or imperfect diet isn’t likely to affect the foetal development during the first week of pregnancy, it’s still a good idea to get as healthy as possible.


To prepare for pregnancy, it’s important to lay a nutritional foundation for foetal development. Because you aren’t always sure if you’re pregnant in the first week, you can start those good habits before you even conceive, according to pregnancy advice website What to Expect. Eating less junk food and increasing the intake of leafy greens will not only aid in your baby’s growth, but you’ll feel better and will be avoiding foods that could make you nauseous or gassy.


If you have been taking over-the-counter medications, prescriptions or herbal supplements, consult with a health care provider, to make sure that they are safe for pregnancy.


The mother’s fitness is important to the health of the baby. Staying fit with 30 minutes of moderate exercise a day will make pregnancy, birth and recovery easier.
