Pregnancy Week by Week – Week 4

In the fourth week of pregnancy the embryo will have two layers of cells namely the epiblast and the hypoblast. These will develop into the baby’s organs and body parts. The amnion and the yolk sac also get developed during the fourth week of pregnancy. The amnion is filled with amniotic fluid which will help protect the embryo by surrounding it. The yolk sac’s function is to produce blood and nourish the embryo until the placenta takes over that role.
During the fourth week of pregnancy the baby gets further implanted into the endometrium. The hormone called human chorionic gonadotrophin(HCG) is secreted by the baby which helps to maintain the lining of the uterus. The ovary is also signalled to stop releasing eggs which stops the menstrual cycle.

Complaints during this stage may include slight spotting or bleeding when the baby gets implanted properly. HCG hormone is generally measured during pregnancy tests. Symptoms of pregnancy like tingling or aching breasts, fatigue, nausea are normally experienced by women during the fourth week of pregnancy when the fetus starts growing. These symptoms augur the fact that your pregnancy is proceeding and you may consult a health care professional to rule out any abnormal complaints or issues at this stage.

A minimum weight gain is observed during this stage which is normal and healthy. Weight gain is also an indicator of your baby’s growth and the extra weight gained is stored for breast feeding your baby after delivery. You should continue to take wholesome foods and dairy products that will aid the growth of the baby.

Regular checkups with the doctor is also advised. The doctor will let you know if the tests are normal or if you have any other symptoms also you can get them cleared with the doctor.
