Pregnancy Trimesters By Week

Pregnancy Trimesters By Week

There are three trimesters of pregnancy. The first trimester is from week 1 to week 12. The second trimester is from week 13 to week 26. The third trimester is from week 27 to the end of the pregnancy.



The first trimester is a time of great change for the mother and the baby. The baby is growing very quickly and the mother’s body is changing to accommodate the baby.

The second trimester is a time of continued growth for the baby. The baby is becoming more active and the mother’s body is changing more.

The third trimester is the time when the baby is fully grown and the mother’s body is preparing for labor and delivery.

Pregnancy Test At 5 Weeks

A pregnancy test at 5 weeks measures the level of the hormone human chorionic gonadotropin (hCG) in your blood or urine. hCG is produced by the placenta shortly after the embryo implants in the uterus. The level of hCG starts to increase rapidly at around the time of the first missed period and peaks around 8-10 weeks of pregnancy.

A pregnancy test at 5 weeks can usually detect the presence of hCG in your blood or urine. However, a positive result is not always accurate. A pregnancy test at 5 weeks is most accurate when used in combination with another test, such as an ultrasound.

Some common early pregnancy symptoms include:

· Frequent urination
· Morning sickness
· Fatigue
· Breast tenderness

As the pregnancy progresses, other symptoms may develop, including:

· Swelling of the feet and ankles
· Increased appetite
· Increased heart rate
· Headaches
· Braxton Hicks contractions

Most of these symptoms are normal and are caused by the changes that are taking place in the body as it prepares for labor. However, it is important to consult with a doctor if any of these symptoms are severe or persist for an extended period of time.

Nausea 36Th Week Pregnancy

Nausea is a common symptom of early pregnancy. It usually begins around the sixth week of pregnancy and ends by the fourteenth week. About 70 percent of pregnant women have some degree of nausea.

There are many theories about the cause of nausea during pregnancy, but the most likely explanation is that it is related to the increase in the level of the hormone human chorionic gonadotropin (hCG) that occurs during early pregnancy. hCG is produced by the placenta and is the hormone that is detected in a home pregnancy test.

Some other theories about the cause of nausea during pregnancy include the following:

• The increase in estrogen levels during early pregnancy.

• The increase in the number of blood vessels in the stomach and the digestive system.

• The increase in the number of lymphocytes (a type of white blood cell) in the stomach.

• The presence of bacteria in the stomach that may cause nausea.

• The increase in the amount of saliva produced in the mouth.

Most pregnant women find that the nausea is worse in the morning and decreases as the day goes on. Some women have nausea all day long. Nausea can be accompanied by vomiting, but not all women who are pregnant vomit.

How Many Weeks Does Pregnancy Last

?

Pregnancy generally lasts about 40 weeks from the time of the woman’s last menstrual period. This is just an estimate, and some pregnancies may last as few as 37 weeks or as many as 43 weeks.

A woman is considered to be pregnant for the nine months following her last menstrual period. The first two weeks of this time period is considered the woman’s menstrual cycle. This means that the baby is only actually 38 weeks old at 40 weeks gestation.

The 40 weeks is divided in to three trimesters. The first trimester is weeks 1-12, the second trimester is weeks 13-27, and the third trimester is weeks 28-40.
