5 Weeks Pregnant: Embryo (Fetus) and Symptoms

Week 5 of pregnancy is when some pregnant women can see the gestational sac of the embryo (which will be called a fetus starting from the end of Week 10 of pregnancy) on the sonogram and start to feel like they’re actually pregnant. Also, as hormone levels fluctuate, various changes occur in one’s body. What is the pregnant mom’s physical condition like in Week 5? How big is the gestational sac?

In Week 5, pregnant moms who have a regular menstrual cycle will notice that their periods are late as it has already been a week since the usual period date. During this period, some will notice that there is slight bleeding – this is called “implantation bleeding” and is one of the very early signs of pregnancy. The bleeding lasts for about three days.

After implantation, pregnancy test kits might give you a positive result. However, test kits are not always accurate, so go to your ob-gyn for a transvaginal ultrasound. When the presence of the gestational sac and the embryo’s heartbeat is confirmed through the ultrasound scan, so is your pregnancy.

After confirming your pregnancy with a pregnancy kit, a transvaginal ultrasound performed by your ob-gyn can help to determine the presence of the gestational sac and the embryo’s heartbeat.

5 Weeks Pregnant: Symptoms appear

● Changes in the early stage of pregnancy
● Breast pain and tightness
● Lethargy and drowsiness
● Lower abdominal pain
● Your body is hot / you feel feverish
● Abdominal tightness, pollakiuria (frequent urination)

As pregnancy causes the body’s temperature to rise above normal average levels, you might feel languid or feverish. This is because progesterone, the hormone which leads to the formation and development of the placenta, is being secreted in huge amounts in your body. Progesterone can cause you to feel tightness in your breasts or feel sleepy.

Also, as the muscles of the uterus stretch and increase, blood flow to the uterus increases. The increase in blood flow causes the mesometrium and the ligaments supporting the uterus to be pulled tight. This might cause you to have lower abdominal pains or feel that your belly is being stretched.

When gases accumulate in the stomach, the number of times one passes gas will increase. As the womb grows, it also puts pressure on the bladder, causing many pregnant women to feel like they have to use the bathroom more often.

The increase in progesterone secreted could have you feeling on edge and you might become more prone to losing your temper, feeling down, or being reduced to tears more easily. During this period of time, it could be helpful to talk to your partner or those around you and seek their understanding, as well as obtain their support so as to be able to go through pregnancy more easily.

At Week 5, the embryo in the gestational sac (the tiny sac inside the uterus) and the embryo’s heartbeat can be detected. It resembles a tadpole, is about 2-5 mm long and is dependent on the yolk sac for nutrients essential for growth. At the end of Week 10 of pregnancy, the baby will be called a fetus.

Week 5 is a period in which the embryo’s organs grow quickly. In Week 5, parts of the face like the eyes, ears, mouth, as well as the organs in the body – including the stomach, intestines, lungs, pancreas, cranial nerves and aorta – continue to develop. Buds that will eventually become hands and legs also start to form.

A chemical pregnancy or an ectopic pregnancy in Week 5?

When a chemical pregnancy or an ectopic pregnancy occurs, a pregnancy test kit will also give you a positive response. A chemical pregnancy refers to the state in which an embryo implants itself in the endometrium (lining of the uterus), but is unable to continue to grow, and pregnancy is not established.

An ectopic pregnancy refers to the state in which the embryo’s implantation is located outside the womb. In instances where the embryo is implanted in the fallopian tubes, there is a risk of the fallopian tubes rupturing when the embryo grows bigger.

If you get a positive result from the pregnancy test kit, it is best that you go to your ob-gyn for a check-up as soon as possible to determine if you are pregnant or not and to rule out the possibility of an ectopic pregnancy.

There is no need to blame yourself if you experience a chemical pregnancy or an ectopic pregnancy because either is unfortunately, unpreventable.
