Pregnancy🤰❤️... Such a beautiful life-giving experience. During this process, the baby develops and grows from the size of a poppy seed to the size of a watermelon🍉. Continue to read and understand how a baby is conceived and the different growing stages👶.
The pregnancy period consists of three trimesters:
Trimester 1: weeks 1 - 13
Trimester 2: weeks 14 - 27
Trimester 3: weeks 28 - 41
The pregnancy process is called the gestation, and it refers to the period of time when conception occurs until the baby is born. Because the time of conception is hard to determine, the gestational period is considered to start from the first day after the end of a menstrual cycle.
Weeks 1 - 4
During the first two weeks the mother is not pregnant yet, as the eggs start to mature inside the ovaries. The ovaries are secreting two hormones, FSH (follicle-stimulating hormone) and LH (luteinizing hormone) causing ovulation by the end of the second week.
The ovulation period usually lasts for 2-3 days, depending on the period of the menstrual cycle. During ovulation one egg is released from the ovary into the fallopian tube.
In the third week, conception is possible during unprotected vaginal intercourse, when a sperm cell travels through the cervix and fallopian tube, where it reaches the egg and fertilization occurs. The sperm cell and the egg unite. Together they form a zygote that travels towards the uterus in the next few days.
In week four, the zygote transforms into an embryo and attaches itself to the uterine wall. During this week, most pregnancy tests will be positive.
The size of the embryo can be compared to a poppy seed.

The fifth week is very important for the healthy development of the fetus. In this period, factors such as medicine, drug use, high alcohol use or some infections can be responsible for birth defects.
During these weeks some organs start to develop as well as the external features.
The heart begins to pump blood and by the end of the eighth week, the heartbeat will be around 120 beats per minute.
After this period the size of the embryo is around the size of a bean, weighing approximately 15 grams.
