5 Weeks Pregnant

If the expectant mother does not inform others about her situation, then at the 5th week no one will notice that she is pregnant. The woman has long experienced symptoms that are unambiguous and specific to her condition.

Rarely does anyone miss the signs of pregnancy at this time. There is a significant delay in menstruation, the chest swells, weakness, and nausea appear. The habitual way of life is changing because in the morning the woman feels unwell.

The 5th embryonic week of pregnancy corresponds to the 7th obstetric week. It is worth distinguishing these terms because many confuse them. Gynecologists often use the countdown from the start of the last menstruation and so they keep a preliminary forecast of the date of birth.

5 Weeks Baby Development

It is at this time that the unborn child is officially recognized as an embryo. He is still very small and details on the ultrasound will not be able to see. There are scientific data that can be used to assess the level of development of the embryo at 5 weeks.

Growth rates do not decrease and further, the rate of embryonic maturation will become even higher. Soon the future baby will be called a fetus.

Data on the parameters of a 5-week-old embryo are relative. It is not yet possible to accurately measure them.

What Size is it?

The embryo of this period is the size of a sesame seed.

Only a small dot on the ultrasound will be visible so it is difficult to determine any additional information.

How Heavy is it?

The weight of a human embryo at 5 weeks does not even reach 1 gram.

It will be possible to determine a more accurate weight a little later. While these indicators are very relative and not accurate.

The umbilical cord is well-formed and already functioning. The placenta is maturing, which serves as the main protective layer for the unborn child.

BrainThe size of the head has increased slightly. There is active growth and development of the brain. It is divided into 3 sections. The hemispheres will continue to form as the embryo develops into a fetus.

HeartThere is a development of the cardiovascular system. The heart is already three-chambered due to the formation of the interatrial septum. The first heartbeats are visible.

LimbsThe body of the future baby in the embryonic form has a definite structure. The neck area is well distinguished, and elbow and knee bends are visible. The arms and legs gradually lengthen, aiming for a more human appearance.

Neural tubeThe active development of the CNS continues. The neural tube is formed. Be sure to take folic acid during this period. It contributes to the proper development of the nervous system and the formation of the neural tube.

Other organs and systemsThere is a confident formation of the digestive organs: the pancreas, liver, intestines, etc. The lungs, trachea, larynx, and even the thyroid gland develop. The reproductive system is developing: the rudiments of eggs are laid in girls and spermatozoa in boys.

The restructuring of the body has a tremendous impact on the well-being of a woman. Life will not be the same in the next month and a half. Toxicosis begins with all its unpleasant symptoms.

Nausea The woman is increasingly sick. This is especially felt in the morning and when hungry. The malaise occurs immediately after waking up. The provoking factor of nausea and possible vomiting can be the smells and tastes of certain foods.

Women develop subjective olfactory intolerance. Many stop eating previously normally used foods. Most often it is fish, pickled foods, meat, and sausage. Everyone has their list of "forbidden" products for this period.

Excessive Saliva Ptyalism or profuse salivation is a clear symptom of early toxicosis. This phenomenon is very common among women in the first trimester of pregnancy. Frequent and strong salivation is accompanied by constant swallowing. This may stimulate the gag reflex.

You can try to reduce this process a little by drinking plenty of water and constantly using snacks.

Frequent Urination The uterus begins to intensively increase in size as the embryo grows and develops. There is a gradual displacement of the internal organs. There is a load on the bladder. A woman experiences a frequent urge to urinate. Going to the toilet becomes a routine during pregnancy.

Headaches A frequent manifestation of symptoms at this time is headaches. Pregnant women complain that they become very weather dependent. The pains have a different character: aching, throbbing, pressing.

Headache has to be endured because of the limited number of permitted medicines. It is recommended to move more, walk more often in the fresh air and try to sleep during the day.

Sometimes you can observe a slight weight loss due to toxicosis. A woman can lose from 1 to 3 kg of weight during this period with severe symptoms. Often there is a deterioration in the condition of the skin. Acne appears, caused by hormonal surges.

Belly size & Health Conditions

There is no visual difference between the belly of a pregnant woman for 5 weeks and a non-pregnant woman. This is an individual score. A woman is likely to notice a slight tightening of the abdomen in the lower part of it if she was initially very thin.

The general state of health is complicated only by the symptoms of toxicosis. This is normal and should not cause much concern for the expectant mother.

General fatigue, weakness, drowsiness, and shortness of breath are quite normal for this period of pregnancy. Now it is more important to ensure that no other symptoms appear outside the norm: severe and sharp pains, blood discharge, or heavy bleeding. It is recommended to immediately seek medical help if such alarming symptoms appear.

Future Mom Tips and Highlights

If toxicosis does not greatly complicate the life of the expectant mother, then most likely she will continue to work during this period. It is worth taking care of yourself especially reverently in the first 3 months of pregnancy. Watch your diet and lifestyle. The development and health of your unborn child depend on this.

Taking a multivitamin – Getting all the necessary vitamins and minerals from ordinary food is very difficult. Support your body with a complex of prenatal vitamins. Better if they are organic.

Avoid stress – Put yourself in a protective “shell” of calmness. Do not get into arguments, stay away from scandals and overly emotional people. Maintain neutrality in all relationships.

Sleep during the day – It is better to take time off from work with severe toxicosis. Take care of yourself and your child. Enter daytime sleep. It will help you gain strength and feel much better.

Fresh air – Keep the window always open if it is not possible to walk daily and for a long time. Oxygen is necessary for you and the development of the unborn baby.

Try to chew all the time – Avoid feeling hungry if you feel sick often. Keep a rescue cookie, cracker, nuts, or hard candy handy. Chewing helps to reduce bouts of nausea.

Beware of viruses – Try to limit your contact with potentially contagious people who attend public events. Tell us about your situation, because it is dangerous for you to get sick now. Relatives should understand that this is temporary.

Remember – everything you do now can affect the development of your baby. Conditionally – you should not ride a horse if you have done it before. Avoid active sports and unsafe pastimes. Now you need to think not only about yourself.

If you don’t smoke, try not to be near those who do. Passive smoking is much more dangerous than active smoking.

Important Checklist

  • Accept all the symptoms of toxicosis as calmly as possible
  • Do not neglect self-help and the help of others
  • Slow down a bit at work
  • Allow yourself to rest more often than before
  • Carefully monitor your well-being
  • Warn loved ones about your situation

Now a new life is developing within you. Its quality and safety depend solely on you. Treat this with full responsibility and patience. Unforgettable moments await ahead: the first meeting with the baby on ultrasound, the first heartbeat, sex determination, and the birth of a child.
