Whether pregnant women can cook with gas stoves is actually less harmful to the human body after burning gas. You don't have to worry too much about this problem. Of course, it is best if pregnant women don't cook, because although the harm of gas is small, it is determined by the cooking habits of China people. When cooking, a lot of oil smoke will be produced, and the harm of oil smoke is quite great.
Precautions for pregnant women in the first three months 1. First month of pregnancy (1 ~ 4 weeks)
If the menstrual cycle of pregnant women is once every 28 ~ 30 days, then the pregnancy time starts from the first day of menstruation, and the second week of pregnancy is not the time for sperm and eggs to combine. After fertilization, the cells continue to divide and soon become solid cell clusters, shaped like mulberry embryos. Cell division occurs when the fertilized egg floats along the fallopian tube to the uterus. About 4 days after fertilization, the pregnant egg reaches the uterus.
In the third week of pregnancy, the outer membrane of the cell mass is removed to prepare for implantation. At this time, the number of cells is about 150, which is divided into two parts: the inner cell mass is the late fetus, and the outer cells will form placenta and amniotic sac in the future. Implant blastocysts into spongy endometrium rich in nutrition and oxygen to complete implantation. At this time, a large number of molecular oxygen, protein, vitamins and other substances in the blood of pregnant women penetrate through the thin villus wall and continuously enter the blood stream of the embryo.
In the fourth week of pregnancy, the blastocyst has been firmly implanted in the human uterus, where it grows and develops into a very small embryo. At this time, menstruation comes. The initial feeling of pregnant women is that their breasts are full and tender. When menstruation comes, it is necessary to consider whether they are pregnant. The third to fourth week of pregnancy is called embryonic germination. The germ is about 0.5 ~ 1 cm long and looks like a small hippocampus. This stage is the growth period of important organs.
2. The second month of pregnancy (5 ~ 8 weeks)
If menstruation returns in the fifth week and the basal body temperature is at a high temperature for more than 16 days, you can go to the hospital for urine test. If the pregnancy test is positive, it can basically be confirmed as pregnancy. At this time, pregnant women began to have pregnancy reactions, such as loss of appetite, anorexia, nausea, vomiting, lethargy, fatigue and chills, and even sentimental and irritable emotions. Some parts of the pregnant woman's body also began to change: breast swelling, nipple and areola blackening, urination and leucorrhea increasing. These phenomena are all physiological phenomena, so there is no need to feel anxious about them. In the second month of pregnancy, the embryo has a body and? Tail? . Can distinguish the eyes, as well as the small ridges on the hands and feet, these small ridges are the future fingers and toes.
In the fifth week of pregnancy, the neural tube of the embryo is gradually formed. These neural tubes will develop into brains and spines in the future. About 7 weeks pregnant: the fetus is about 2 ~ 3 cm long and weighs about 4 grams. It has grown hands and feet, and its eyes, ears and mouth can also be seen roughly. The face looks like a person at first.
3. The third month of pregnancy (9 ~ 12 weeks)
When the pregnancy enters the ninth week, the facial features of the embryo are obvious, the body of the embryo is elongated and straightened, and the tail is shortened and disappeared. By the tenth week, the embryonic period is over and the fetus is entered. The human characteristics of the fetus are clearly displayed, and both fingers and toes can be seen. The umbilical cord is getting longer and longer, and the fetus can rotate freely in amniotic fluid. At this time, the heart, liver, stomach and intestine of the fetus are more developed, and the kidneys are gradually developed, resulting in urine. Together with the ureter, the fetus can carry out trace excretion.
By the eleventh week, the pregnant woman's uterus is as big as a fist. If it is pressed around the uterus, there will be a feeling of lower abdominal pressure or heel cramp, and the number of urination will increase. At this time, the pregnancy reaction gradually decreases and will soon disappear. Pregnant women will feel more swollen breasts at this time, and there will be pigmentation and black on the areola and nipple.
During this period, pregnant women are prone to constipation and diarrhea. This period is the most prone to miscarriage. Pregnant women should stop strenuous exercise and physical labor and should not travel. At the same time, we should pay attention to avoid pressing the abdomen. If pregnant women have lower abdominal pain and a small amount of bleeding during this period, they should immediately seek medical examination, because there is the possibility of miscarriage and ectopic pregnancy, so don't let your guard down.
Precautions in the third trimester 1. Sleeping position in the third trimester: It is best to sleep on the left side in the third trimester and keep the legs on the bed bent. The abdomen is attached to the bed, which makes you feel more secure. For expectant mothers who often have swollen legs, if they lie on their side, they can put pillows or pillows under their legs to raise their legs. In this way, the blood circulation of the legs becomes better and fatigue is reduced. Avoid sleeping on your stomach or lying flat during pregnancy. Sleeping on your stomach, abdominal pressure is not good for the fetus and pregnant women; Sleeping on your back in the third trimester, the enlarged uterus will compress the spine and hinder blood circulation.
2, stomach pain: in the third trimester, when the expectant mother rests at night, she sometimes has abdominal pain due to false contractions, which usually lasts only a few seconds, with no feeling of falling to the ground, and the symptoms can be alleviated during the day. If the expectant mother suddenly feels persistent pain in the lower abdomen, it may be premature delivery or threatened rupture of the uterus. You should go to the hospital in time, and you must not delay.
3, diarrhea: once the expectant mother has diarrhea, the main treatment is to properly replenish water, make up for the water and electrolytes lost due to diarrhea, especially potassium ions, and supplement the heat lost due to diarrhea. At the same time, we should closely observe whether the fetus is in good condition and whether there are signs of premature delivery.
4, the third trimester recipe: near the end of pregnancy, the fetus will go down to the pelvic cavity, so when the gastrointestinal pressure is small, the appetite will be strong again. Mothers in the third trimester should increase the intake of protein and eat as much animal protein and soy foods as possible. You also need to take in the right amount of essential fatty acids and eat some animal livers to supplement iron.
5, fetal poison: Chinese medicine believes that fetal poison is mainly wet poison and heat poison, which is accumulated by the mother during pregnancy, which may lead to eczema after the baby is born. Expectant mothers should eat a reasonable diet throughout pregnancy, not only to eat some complementary foods to ensure the intake of nutrients, but also to eat more fresh vegetables and fruits to ensure the intake of various nutrients and keep the stool unobstructed. Pregnant women are not advised to eat food containing drugs or medicinal materials.
6, fetal movement: If the fetal movement is frequent in the third trimester (fetal movement is greater than or equal to 30 times/12 hours or greater than or equal to 4 times/hour) is also normal, so expectant mothers don't have to worry too much. According to different time, the number of fetal movements will also change. Generally speaking, fetal movement is more at night and less in the morning.
7. Edema: Expectant mothers with edema in the third trimester should pay attention to their diet, eat more fruits and vegetables and eat less foods with high salt content, which will help to reduce swelling. No matter what causes pregnancy edema, drug treatment can't completely solve the problem. We must improve nutrition, increase the intake of protein in diet, increase the content of albumin in plasma, and change the colloid osmotic pressure, so that the water in tissues can return to the blood.
8, pubic pain: near the delivery time, expectant mothers will secrete a hormone called thyroxine, which will make it easier for the fetus to pass through the birth canal, and the pubic junction will be more relaxed. At this time, the head of the fetus will be oppressed by the pubic bone, and the pelvis seems to fall off, which will feel very painful. The pain starts in the second half of pregnancy and gradually increases until delivery. This pain will disappear after the baby is born. When the pain is severe, lie down, try not to be oppressed by the pubic bone and have a good rest.
9. Constipation: Constipation in the third trimester is a normal phenomenon. Expectant mothers should walk more every day, exercise, drink more water and not eat greasy food. You can do more anal exercise every day, which is helpful to exercise muscle groups, assist intestinal movement and relieve constipation.
10, shortness of breath during pregnancy: In the late pregnancy, because the enlarged uterus exerts pressure on the diaphragm, you will feel that breathing is more laborious, and the phenomenon of shortness of breath is more obvious, especially if the fetal position is higher or you are pregnant with multiple births. Shortness of breath during pregnancy is usually nothing serious and normal. In daily life, you can slow down the pace, and don't force yourself too much when you are active or exercising. Keep your upper body straight, spread your shoulders back and let your lungs spread as far as possible, especially when sitting. When you sleep at night, using more pillows will make you feel better.
1 1. Finger joint pain: Pregnant mothers in the third trimester often have wrist and finger joint pain. This is because in order to meet the needs of childbirth, the body will secrete a lot of relaxation hormones to increase the flexibility of the body, which will lead to the edema tendon in the joint area becoming fragile and painful, thus causing pain. I suggest you take more rest and minimize the stimulation of your opponent's knuckles.
12, frequent contractions: If the expectant mother stands or sits in the same posture for a long time, she will feel the abdomen hardening. What is the situation? Fake contract? . Especially when expectant mothers feel tired or excited, this phenomenon is more likely to occur, which is one of the signs of approaching delivery, but unlike real regular prenatal contractions, it often appears within 2-3 weeks before delivery. False contractions are frequent, so expectant mothers should not take medicine by themselves, and taking medicine can generally not be alleviated. At this time, pregnant mothers should pay attention to rest, especially not to stimulate the abdomen. If uterine contraction is accompanied by intense abdominal pain, such as fidgeting, work and life are affected, you need to go to the hospital.
13, into the basin: After the fetus enters the basin, you will have obvious contractions, and some people will feel frequent urination. The delivery time is generally from the 36th week of pregnancy to the arrival of labor pains. Primiparas usually enter the basin two weeks before the expected date of delivery, while multiparas usually enter the basin before the onset of labor pains, but some women complete the whole process within a few days.
