The problem of sex during pregnancy is a common confusion among women, but because of the sensitivity of this topic, many women are ashamed to talk about it. Pregnancy is a special period for women, all organs and systems in the body will undergo a series of physiological changes, but also a “special period” of sexual life, most women’s sexual desire will be reduced. The change in sexual desire during pregnancy can be caused by psychosocial factors and lifestyle changes, and also has a certain relationship with the large changes in sex hormone levels during pregnancy. The requirements for sexual life vary at different stages of pregnancy. Early Pregnancy: Red Light Before 12 weeks of pregnancy (the first 3 months of pregnancy) should avoid intercourse. At this time, the placental villi are immature, the embryo and the uterine meconium are not yet firmly connected, for a good period of miscarriage. Uterine contractions are likely to occur during orgasm, increasing the risk of miscarriage. Pregnant women with a history of miscarriage, those who have had a small amount of vaginal bleeding during pregnancy, and those who are older should be prohibited from having sex. In addition, pregnant women in early pregnancy often have different degrees of early pregnancy reactions, such as weakness, nausea, vomiting or loss of appetite, etc., so the interest in sex will be reduced, the spouse should understand, care and considerate wife. Mid-pregnancy: yellow light Mid-pregnancy refers to the 12th to 27th week of pregnancy (4 to 7 months of pregnancy). This period can be intercourse, but in order to avoid pressure on the pregnant uterus and fetal involvement, must be properly adjusted to the position, position and time of sexual life. For example, you can take the female lying down, buttocks on the edge of the bed, the spouse standing position to carry out or side lying position, the action should be gentle. Pregnant women with gestational hypertension should abstain from sex in order to avoid a rise in blood pressure. Pregnant women with anterior placenta should also abstain from sex in order to prevent intercourse from stimulating uterine contractions and causing bleeding. Late Pregnancy: Yellow Light The 28~36 weeks of pregnancy (7~9 months of pregnancy) belongs to the late pregnancy period. Due to the rapid weight gain, abdominal enlargement and increased load on the whole body, it brings inconvenience to daily life and activities and low sexual desire, so the frequency of intercourse should be reduced. The last 4 weeks of pregnancy: red light The last month of pregnancy, sex should be strictly prohibited, because at this time intercourse can cause fetal membranes, increasing the risk of premature rupture of fetal membranes, preterm delivery and puerperal infection. The correct posture of sex during pregnancy 1, within 3 months of pregnancy normal position: because the abdomen has not yet become large, so in the early stages of pregnancy can also be used in the normal position, so that neither the pressure on the abdomen, but also not penetrate too deep. Crossed position: the male slightly side after the combination of crossed position, also will not penetrate too deep, is also a more suitable position. Elongated position: the elongated position that can experience the interest, will not cause pressure on the abdomen, but also will not penetrate too deep. 2, 5-8 months of pregnancy rear side position: male and female lying on their sides in the same direction rear side position will not bring pressure to the fetus, and can increase or decrease the depth according to the male’s wishes, so it is a suitable position for the middle of pregnancy. This position will not damage the vaginal or uterine opening and will not cause allergies. It is also possible to replace penetration with other auxiliary movements, such as caressing the breasts, which can increase satisfaction. Anterolateral position: The anterolateral position, where the man and woman are lying on their sides facing each other, does not compress the abdomen nor is it too deep. Front sitting position: This is a position where the woman and the man are sitting, so there is no pressure on the abdomen, and the depth of the union can be adjusted, making it a safer position. Back position: the back position, in which the man supports the woman’s upper body from behind, does not exert weight on the woman’s body and can adjust the depth at will. 3, after the eighth month of pregnancy rear side position: the man needs to hold the woman behind the woman, and do not press the belly of the position. Backseat position: the woman sits on the lap of the man who is sitting, with her back against the man’s position. The man needs to adjust the length and speed of penis entry, and try not to stimulate the action too Tips: Sex can trigger uterine contractions due to the following factors, which may affect the normal process of pregnancy: 1. Direct stimulation of the cervix, causing uterine contractions. During pregnancy, the uterus increases in size, the pelvic support tissue relaxes, and the cervix moves down; in late pregnancy, the fetal previa descends and enters the pelvis, and the cervix then descends. 2.Orgasm causes contraction of the uterus. 3.Prostaglandins and chemicals in semen stimulate uterine contraction. 4.Stimulation of breasts and nipples can also induce uterine contractions.
