First Week of Pregnancy: Symptoms Before Missed Period

First Week of Pregnancy: Symptoms Before Missed Period

In general women don’t even realize they are pregnant during the first week of pregnancy. Many of them don’t realize they are pregnant even during the second week. Mostly pregnancy is discovered while being three weeks pregnant. The menstrual cycle varies among women, so most women assume that their cycle is just late. As there are no obvious signs and symptoms of pregnancy during the first week, it is normal not to realize that you are pregnant. However, certain signs and symptoms are present, but women mostly attribute these signs and symptoms to PMS. Fatigue, mood swings, loss of interest in things and a constant need to urinate may be present.

Pregnant or Non-pregnant

Certain Brooklyn gynecologist think that a woman is not pregnant during the first week as the fertilization has not occurred yet. Fertilization takes place during the second week of pregnancy. During the first week the egg leaves the ovary and travels toward the Fallopian tubes. In the Fallopian tubes the egg gets fertilized by the sperm and afterwards travels into the uterus where the implantation occurs. However, the first week of pregnancy is included in the pregnancy calendar as it helps your doctor to calculate the first day of your last menstrual period (Readalso: pregnancy calculator). Keep in mind that a normal menstrual cycle lasts approximately 28 days. Some women have shorter menstrual cycles as 24 days, while others have longer menstrual cycles up to 35 days.

What Happens During the First Week of Pregnancy

Once the egg is fertilized the cells begin to divide over the next 7 – 10 days. These cells are called blastocysts during the first week of pregnancy. Blastocysts divide into two parts, into the external part which later will become the placenta and the internal part which later will become the embryo. This process occurs during the travel of the “embryo” from the Fallopian tubes into the uterus. Usually, the embryo is implanted into the inner wall of the uterus after 7 days from fertilization, which corresponds with the second week of pregnancy.

Hormonal Changes During the First Week

As mentioned before, the first week of pregnancy usually passes unnoticed and the signs and symptoms appear only after the second week of pregnancy. However, fatigue, breast tenderness, mood swings, morning sickness, constipation and other digestive problems are possible. They all result from the hormonal changes that the body undergoes during the first week of pregnancy.

If you and your partner are planning to get pregnant, monitoring your morning basal body temperature is recommended as one of the early signs of pregnancy. You will notice that your temperature will remain elevated even after the 16th day of your menstrual cycle. Elevated level of morning basal body temperature is the first physiological sign of pregnancy.

Tips for Early Pregnancy

If you suspect that you are pregnant consult your health care provider ofBrooklyn Abortion. Start taking vitamins and minerals such as folic acid as they are necessary for your baby to grow. Consult your health care provider for any medication that you may take. Maybe they are not safe to be used during pregnancy as most of the medications available for treating various chronic medical conditions are harmful to the baby. Your doctor will require for you to switch or even quit the medication that you might be taking.
