Pregnancy is the time taken for a fetus to develop inside a woman’s womb. Sometimes, if more than one embryo develops inside the uterus at the same time, it is known as a multiple pregnancy. It typically lasts for 40 weeks from the last menstrual period (LMP). A woman can get pregnant through sexual intercourse or by Assisted Reproductive Technology (ART).
A few symptoms of pregnancy are noticeable early on, these symptoms include:
If you develop any of the above symptoms, it is best you get a pregnancy test done. Pregnancy tests usually detect the presence of hCG (human chorionic gonadotropin) hormone in the blood and urine. This hormone is produced after implantation.
The various pregnancy tests available are:
Pregnancy is divided into three trimesters, the first, second, and the third trimesters.
Weeks 1 to 12 is the first trimester. It includes the process of fertilization, that is the process of sperm and ova forming an embryo in the fallopian tube. This embryo then travels down and reaches the uterus and gets attached to the wall of the uterus (implantation). This is the period where the embryo and placenta start to grow in the womb.By around 4 to 5 weeks, your baby’s heart, brain, and spinal cord start forming. Arm and leg buds can be seen. By 8 weeks, all major organs and external body structures start forming. The developing heart begins to beat in a regular rhythm. The umbilical cord is clearly visible, and the fetus is an inch long and looks more like a human. And by the 12th week, the nerves and muscles form and work together. The external sex organs start developing, and the eyelids close to protect the developing eyes. At the end of 12 weeks, the fetus is approximately 3 inches long.
Your body undergoes many changes, and hormonal changes affect almost all the organs of your body. The first sign of pregnancy is your periods stopping. The symptoms of pregnancy can start from the first week itself, but some women might not feel any discomfort at all.
The signs are:
Weeks 13 to 28 is the second trimester. Majority of pregnant women find this trimester easier than the first. The baby starts growing, and your abdomen and uterus expand with it. By the end of this trimester, you can feel your baby move inside you.Generally, by the end of the 16th week, muscle and bone grow and form a complete skeleton, and transparent skin begins to form. The baby’s first bowel movement (meconium) develops in their intestinal tract. By the 20th week, the developing fetus is covered with fine hair (lanugo). The baby becomes more active, and you can feel slight fluttering movements. Eyebrows, eyelashes, and nails form. At 24 weeks, the bone marrow starts making blood cells. Fingerprints, footprints, and taste buds develop. Hair starts growing, and the sex organs develop. By the end of the second trimester, the fetus is approximately 12 inches long.
Weeks 29 to 40 is the third trimester. It is the final stage of pregnancy. As the baby grows, it might put more pressure on your internal organs. You might have difficulty breathing and might urinate frequently. These problems should go away after you give birth.By the 32nd week, your baby’s bones are soft but fully formed. As a result, their kicks and jabs are more forceful. The fine hair covering their body falls off. The eyes open and close and can sense changes in light. At 36 weeks, the body fat increases and protective wax coating (vernix) gets thicker. Your baby is about 16 to 19 inches long. At 39 weeks, your baby is considered full-term. The baby’s organs are fully formed and can function on their own.
The discomforts felt during the second trimester may continue, also the following symptoms may be present:
Due Date: The due date or estimated date of delivery (EDD) is the expected date of delivery for pregnant women. A normal pregnancy lasts for 280 days, and it is calculated from the last menstrual period (LMP).
Normal labor starts as early as three weeks before or two weeks after the due date. The following are the signs of labor:

Pregnancy is a significant time during a woman's life. It is crucial to take care of yourself during these 9 months, as any changes in the health will have a direct effect on the developing fetus.
