4 Weeks Pregnant

This is a crucial period of development during a pregnancy. At 4 weeks pregnant and onwards it is best to avoid contact with any substances which may harm the fetus, such as toxins and pollutants.

Tobacco and alcohol are the main substances to cause malformations and deformities in the fetus. Any form of substance abuse can harm the fetus. Speak with your doctor if you have any addictions. They will be able to give information on support groups and offer a plan of action. Should you come into contact with any hazardous products which may affect the fetus development contact your doctor.

Pollutants within the environment cause as much harm as the other toxins which may be ingested during a pregnancy. The common pollutants which can affect the development of the fetus are: Pesticides, mercury, lead and PCBs (these are a mixture of chemical compounds). Make sure that your work environment is safe.

The fetus is extremely small at 4 weeks pregnant and as the fetus grows the placenta will give nourishment and support to the baby for the 9 months of the pregnancy. This stage is often referred to as the embryonic period. Throughout this stage, also known as implantation other symptoms may start to be experienced at this time.

Some women at 4 weeks pregnant report changes in the body and begin to feel more tired.


At this stage the fetus is aiming to embed itself into the uterus lining. Cramps can be expected at this time and usually it is no cause for concern. But if the cramps occur with a fever, chills or vaginal bleeding which is heavy, contact the doctor immediately. Light spotting shows as light brown or pink. If it appears bright red or heavy and looks similar to a menstrual period contact the doctor.

Vomiting and nausea can be experienced at 4 weeks pregnant. But it generally tends to happen at 6 weeks pregnant. Smells from tea or coffee may make you feel squeamish and there may be certain foods which you thoroughly enjoyed before pregnancy but now the smell makes you feel sick and nauseas. The nausea will more than likely become worse as the pregnancy goes on. It is normally in the second trimester that the sickness disappears.

Swollen and tender breasts are to be expected at this time. Another symptom at the early stage of pregnancy is the need to urinate more. This is due to hormones. After conception more blood flows through the kidneys which make the bladder fill up and become full more frequently.

At 4 weeks pregnant the weight gain is under a 1lb and the pounds will be put on as the pregnancy progresses. By 40 weeks pregnant the weight gain will be approximately 25 and 35 pounds.

During pregnancy be aware of your nutrition. Find out what foods are good to eat when pregnant and also what foods to avoid.
