Having children has become a goal for all married couples. No wonder there are various ways to get pregnant, ranging from natural methods to using medical procedures such as IVF. But have you ever thought, how does the process of pregnancy occur after intercourse?
Pregnancy is the process of developing a fetus in the mother’s womb. However, before that, a long process must be passed until pregnancy occurs. Pregnancy can also only happen if the couple has good fertility so that fertilization can occur.
The occurrence of pregnancy begins with sexual activity between a man and a woman. In the process, the man will release sperm cells, looking for egg cells to fertilize it. If the fertilization is successful, then the woman will become pregnant. A fetus will develop in her uterus for approximately nine months before finally being ready to give birth.
Here are five steps of pregnancy in women starting from intercourse until the fetus is fully developed in the mother’s womb.
1. Sperm Cell Journey
The process of pregnancy begins when a male and female engage in sexual activity. At that time, men usually release seminal fluid containing sperm cells into the woman’s vagina. Furthermore, the sperm cells, with the help of mucus from the vagina, will enter the uterus to find the egg and do fertilization.
In one ejaculation before pregnancy after frequent intercourse, a man can release 300 million sperm cells, but only a few can make it to the cervix. Usually, after a long journey, only 200 sperm cells are left ready to meet the egg. From this number, only one sperm cell with the highest quality will succeed in fertilizing an egg in the uterus.
A woman can only produce one egg every month. Besides, you cannot predict which tube contains a mature egg, whether right or left. This is what makes the sperm cells have to fight hard to find the egg and carry out fertilization.
After struggling through obstacles and a long journey, the most powerful sperm cell will finally meet the mature egg cell in the Fallopian tube. Even though they have met, the fertilization process may not necessarily occur because the sperm cells still have to fight back to penetrate the egg.
The fertilization process can be successful if the sperm cell has succeeded in penetrating the egg cell wall. Usually, the process of fertilization or how long the pregnancy process after having sex occurs is approximately 24 hours. However, if the fertilization process is not successful, then the egg will get away from the uterine wall and fuse out of the vagina or commonly known as the menstrual cycle.
3. Zygote Formation
If the egg cell fertilization by the sperm cell succeeds, then the egg cell will develop into a zygote. In this step, the cells will double every twelve hours until the zygote manages to reach the uterus. This zygote formation can be one of the pregnancy characteristics after four days of intercourse and successful fertilization.
When the zygote succeeds to develop, usually, women start to show pregnancy symptoms even though not so visible. Then the zygote will continue to develop, and on the seventh day, it will reach the uterus and develop and grow into a perfect fetus.
Furthermore, the zygote that has reached the uterus will continue to develop until it has 500 cells, and this hollow layer will start the implantation process. This is the process of attaching the zygote to the uterine wall. This process of attachment of the zygote will usually cause the uterine wall to become inflamed and injured so that bleeding appears as a physical feature of successful fertilization.
Furthermore, the hollow pouch that has been formed will continue to develop until it becomes the amniotic sac and the placenta. Later this bag will be a place of nutrition for the fetus as it develops to grow healthy and perfect.
5. Embryo Development
After passing the implantation period as a sign of pregnancy after one week of intercourse, and the process of forming the amniotic sac and placenta, the fetus will begin to develop in the uterus as gestational age increases. The stages of fetal development are usually divided into three stages according to gestational age, namely the first trimester, second trimester and third trimester.
- First Trimester
If there are no physical signs of failed fertilization, fetal blood cells begin to form in the first trimester or the 3rd week of pregnancy, and blood circulation has also started. Furthermore, at week 4, the fetal heart tube has begun to form and can beat.
At week 6, the shape of the face and throat of the fetus has begun to form. Meanwhile, at the 7th week, the hands and feet of the fetus also start to develop so that the uterus is now double in size. In the 8th to 10th week, the fetus has successfully passed the critical period, and its body structure is also complete. Furthermore, at the 11th to 13th week, the baby’s brain also develops rapidly. So can you get pregnant after two months of intercourse? The answer is no because sperm cells can only survive seven days in the uterus.
- Second Trimester
In the second trimester, the average condition of the fetus and mother’s womb is relatively stable and robust. This is because the organs and structures of the fetus have also become more perfect so that they are more robust. At the 14th to 15th week, the sense of taste in the fetus has also begun to form. At the 16th to 18th week, the development of the fetus will be very significant where the genitals are also well developed.
Entering the 20th to 27th week, the fetus is growing very rapidly, and even the fetus begins to move in the mother’s womb actively. The fetus also begins to learn to open its eyes, suck fingers and even hiccup. You certainly won’t feel this sensation from whether one day after intercourse you can know you are pregnant.
- Third Trimester
In the third trimester, the baby’s weight usually reaches 1 kg. Not only that, the baby’s muscles and lungs have also developed quite well. Entering the 31st to 33rd weeks, the baby will be more active by giving kicks, and even the mother often experiences false contractions.
Entering the 34th to 35th week, the baby’s brain and vital organs are mature and perfect. From here, there is no longer a chance to prevent pregnancy after intercourse because, in a few weeks, the baby is ready to be born into the world. Week 39 is usually the baby’s time to see the world. Signs of birth typically begin with the rupture of the membranes and continuous contractions. If you experience this, immediately come to the hospital to give birth.
The process is quite lengthy and complicated. However, it is not necessarily a pregnancy if you experience nausea after three days of intercourse. So to be sure, it would be better if you check with your obstetrician directly, or you can also do your pregnancy test using a test pack first.
That’s the process of pregnancy that you need to know. As explained above, the process of pregnancy after intercourse is quite long, complicated and takes a long time. Therefore, it is appropriate for us to take good care of and maintain a pregnancy to grow up healthily and flawlessly.
