Pregnancy Week 5

At almost the size of a grain of rice, pregnancy week 5 sees the continuation of the development of the baby’s organs. During week 5, the different chambers of the heart begin to divide and start to actually pump blood. The middle layer of cells, the mesoderm, forms into the heart, the muscles, cartilage, and bone. Therefore, there is the possibility of skeletal structures forming during this week. The placenta and umbilical cord continue to develop as the top layer of cells form the neural tube. The top layer also yields the skin, nails, hair, and sweat glands of the baby. The endoderm, or the third layer of cells in the developing baby produce the lungs, intestines, thyroid and pancreas.

Bloating is one symptom related to week 5. Nausea becomes an indicator of pregnancy during this week along with an increase in the need to urinate more often, and soreness in the breasts. Despite these common symptoms, the most prevailing symptom at week five is fatigue. Fatigue is common during the entire pregnancy but is usually worse in the early weeks. Exercise such as a brisk walk around the block in fresh air is the best way to combat fatigue during these early stages. Coffee or other caffeinated products can potentially harm the developing fetus.

Some things to watch out for during early pregnancy can help avoid complications and future impairments. An ectopic pregnancy is when the fertilized egg implants outside of the uterus, generally in the fallopian tube but possibly in the ovary or cervix. The chances of having an ectopic pregnancy are about one in one hundred and increase if there is a history of pelvic inflammatory disease and if the woman has already experienced an ectopic pregnancy. Major signs include vaginal bleeding, abdominal pain, and nausea. Because these symptoms often resemble regular pregnancy signs, the best way to identify an ectopic pregnancy is by measuring the levels of HCG in the blood, or by having an ultrasound done. Any abnormal symptoms should be discussed with the family prenatal care provider.
