Pregnant mothers and their families may as well know the relevant knowledge in pregnancy in advance, understand what changes pregnant mothers will have in pregnancy is a normal phenomenon, then they can accept it calmly and easily spend this long pregnancy. < / P > < p > since she became pregnant in March this year, even in the hottest months of July and August, her best friend Xiangxiang has resolutely refused to wear sleeveless or sling maternity clothes. We are all very curious. After all, Xiangxiang specially bought many beautiful sleeveless maternity dresses or skirts before she became pregnant, because it is said that pregnant women will be afraid of heat after pregnancy. So I asked her why in the wechat group. < / P > < p > Xiangxiang said helplessly that her armpit suddenly became very dark after two months of pregnancy. At first, she thought that there was something wrong with her body, so she went to the hospital for examination. Unexpectedly, the doctor told her that the reason why her armpit turned black was because she had enough progesterone and progesterone in her body, which was also a symbol of the healthy development of the fetus. Let Xiangxiang not worry. And doctors also said that after the baby was born, progesterone and progesterone returned to pre pregnancy levels, her armpit will slowly return to normal state. < / P > < p > I believe that many pregnant mothers also have this situation in Hunan. Some pregnant mothers’ nipples, areola, private places and other private places will also turn black. These are caused by increased hormones and melanin deposition in the body. Well, in addition to blackening, there are many changes in the body of pregnant mothers during pregnancy. < / P > < p > after many pregnant mothers are pregnant, their eyesight will become blurred, and there is a feeling of vision decline. Some pregnant mothers even have dry eyes, fatigue and other similar symptoms of dry eye. < / P > < p > after pregnancy, the corneal radian of some pregnant mothers will become steeper than usual, so their vision will decline. At the same time, because of the increase of lutein, the body appears edema and congestion, leading to dry eye. < / P > < p > pregnant mothers sometimes have gingival congestion or bleeding, accompanied by swelling and pain. Some pregnant mothers with strong reactions will have loose teeth. < / P > < p > during pregnancy, as long as some pregnant mothers are sedentary, they will feel sciatic nerve pain, and the bones in the thighs and buttocks will also have obvious pain. < / P > < p > I believe many pregnant mothers have found that since they are pregnant, their fingers, arms and legs will become much thicker, which is difficult for pregnant mothers who love beauty. < / P > < p > after pregnancy, the limbs become strong, mainly because the pregnant mothers’ uterus pressed the main vein, making the body appear edema phenomenon. Moreover, during pregnancy, progesterone can relax the blood vessel wall of the pregnant mother, resulting in insufficient closure of the venous valve, hindering the direction of blood flow back to the heart, and causing varicose veins in the legs. < / P > < p > of course, in addition to the above phenomena, after pregnancy, the buttocks of pregnant mothers will become wide and thick, there will be a line in the center of the stomach, pregnancy marks will grow, butterflies will appear on the face, and the face and neck will turn black. These are very common phenomena during pregnancy, so pregnant mothers need not worry too much. < / P > < p > pregnant mothers should not reduce the amount of water they drink even if they urinate frequently during pregnancy. They should ensure enough intake every day. This can promote the excretion of toxins or other harmful substances in the urethra in time. Of course, before going to bed should try not to drink water, this can greatly reduce the burden of the kidney. < / P > < p > during pregnancy, pregnant mothers try not to eat some fried, high calorie food, eat a light diet, and eat enough fresh fruits every day to ensure that there is no lack of vitamin C in the body. At the same time, we should also pay attention to adequate intake of vitamin B, protein, iron and calcium. < / P > < p > pregnant mothers must keep a happy mood during pregnancy and try not to have too much emotional fluctuation. Ensure adequate sleep, proper exercise, improve their immunity. It’s very hard for women to conceive in October. During pregnancy, due to the influence of progesterone, estrogen and other hormones, pregnant mothers not only have physical changes, but also have big or small fluctuations in psychology and mood. While pregnant mothers pay attention to self adjustment, expectant fathers and their families should also help pregnant mothers, fully understand their hard work, and create an optimal breeding environment together. After pregnancy, do not let the wife do these five kinds of housework, the husband should be responsible for it, otherwise it is easy to hurt the fetus!
