The health of the pregnant woman and fetus in the third trimester of pregnancy
The period of gestation from fertilization of the egg until birth extends to 40 weeks, and according to the changes that occur in the pregnant woman and the growth and development of the fetus, this period is divided into three stages:
- The first stage lasts until the 12th week.
- The second stage extends from the 13th to the 28th week.
- The third stage extends from the 28th week until birth (the 40th week).
- Each stage is essential for the changes in the pregnant woman’s body and the growth and development of the fetus.
Changes in the third trimester of pregnancy
- The pregnant woman feels an increase in the size of the abdomen and breasts in the 3rd trimester, false uterine contractions, an increase in the number of urination times due to pressure of the uterus on the bladder, and the lowering of the tip of the upper abdomen in the last weeks, which indicates the descent of the fetus to a low level in the pelvis in preparation for its exit.
- The movement of the fetus increases to complete its growth and increase its vitality, and the head is directed down or up, defining the method of birth.
- The baby’s length is 45-50 cm, weighing about 3 kg.
Fetal movement:
- The pregnant woman is supposed to feel the movement of the fetus every day, not an hourly condition, as fetuses have sleep cycles while they are in their mothers’ wombs, and it may last for two hours or more, during which their movement is minimal and imperceptible.
- The mother can stimulate the activity of her fetus by eating a snack or drinking juice, which will make him more active and moving.
- But if she still does not feel the movement of her fetus, she should consult a doctor to ensure the fetus’s health by listening to his heartbeat.
- Skin color change: is it normal? Yes, some areas of a pregnant woman’s skin change to a darker color in the 3rd trimester, such as the nipples, the face area, and the pubic area, and then usually lighten after childbirth.
Having intimate relationships in the third trimester of pregnancy
● Having sex during the last three months, is it safe? Sex is essential for a couple to maintain intimacy and is a normal and healthy activity during pregnancy.
● Practicing intimate relations between spouses throughout pregnancy is safe unless the doctor advises not to practice it for specific reasons in pregnancy, such as the presence of complications such as bleeding, placenta previa, or rupture of membranes near childbirth.
● In the event of fear and anxiety about the possibility of infection with one of the sexually transmitted diseases from the husband, the husband should use a condom.
● Some pregnant women experience discomfort, pain, and abdominal cramping during private practice with their husbands.
● This occurs because the cervix is affected, which leads to uterine spasms. This is normal and has no effect on the child or fear of childbirth; you can mitigate this by taking certain positions that reduce the depth of the penis into the vagina.
Does nausea occur in the third trimester of pregnancy?
- Morning sickness has returned in recent months.
- Nausea often returns in the last trimester of pregnancy due to the large size of the uterus, which presses on the stomach and displaces it from its normal place, delaying emptying the stomach’s contents, which leads to nausea. The pregnant woman feels heartburn with symptoms of nausea for the same reason.
- A pregnant woman may complain of a lot of gas in her stomach and an increase in the number of urination times, as it was at the beginning of pregnancy, which is expected in the 3rd trimester, and the reason is that the fetus moves down the pelvis in preparation for birth.
- In addition to the feeling of tightening in the abdominal area and the beginning of light cramps and cramps (false labor), then turning them into painful contractions, and it may be a sign of childbirth.
Conclusion
The 3rd trimester of pregnancy or third trimester of pregnancy lasts approximately 40 weeks. The third trimester includes weeks 28-40 of pregnancy and is physically and emotionally challenging for pregnant women.
