Is the fetus stable in the fourth month of pregnancy? At the third month of pregnancy, the degree of fetal stability is relatively low, and after four months, that is, in the second trimester, it is relatively stable, but there is still the danger of miscarriage, so you need to pay great attention to it, and you can't do gravity work. In the third trimester, the stomach is relatively large, so it is not as convenient to move as in the second trimester, but the center of gravity is forward, so it is best to ban sexual life in the first and third trimesters.
During pregnancy, expectant mothers will undergo great changes both physically and psychologically, so we should adjust our mentality as soon as possible. After three months of pregnancy, the pregnant mother's appetite began to increase, and the lost weight gradually picked up because of the increase in appetite. Due to the influence of pelvic congestion and persistent and vigorous secretion of lutein, vaginal secretion is slightly higher than that of non-pregnancy.
Check it every four weeks in the second trimester. Before the second trimester (13 weeks), build a small card, 16 weeks, do a B-ultrasound,16 ~ 20 weeks, do a down's screening, and if it is high-risk, do a sheep puncture (amniocentesis, optional) for 22 ~ 20 weeks.
At the same time, pregnant women will have frequent urination and always feel that the urine is not clean. The breast will also swell, because the changes of hormones in the body begin to grow further, and the areola and nipple pigmentation are more obvious and the color turns black. In short, it is very necessary to know all kinds of changes that may occur during pregnancy in advance. Knowing that this is a normal phenomenon in pregnancy can avoid unnecessary anxiety and maintain a happy mood.
How old is the fetus after four months of pregnancy? When entering the second trimester, I believe many pregnant moms will have such feelings. The morning sickness has slowed down, and even they can feel the fetal movement in their stomachs. It is really a little excitement! This is a common pregnancy reaction in the fourth month of pregnancy, so what is the fetal development at this time? Let's take a look together.
Four months pregnant 13 weeks: the fetal length is 7.5-9.5 cm, the fetal body shape has been fully formed, and the facial features are very obvious.
Four months pregnant 14 weeks: the fetal length is 7.5-10 cm, and the fetal weight is about 28g. The fetal facial features are clear.
Four months pregnant 15 weeks: fetal length 10cm, fetal weight about 50g, and the fetus is very active.
The fourth week of pregnancy (pregnancy 16 weeks): the fetal length is 12cm, and the fetal weight is about 150g. At this time, the fetus is very small and the size is just in the palm of your hand.
Generally speaking, in the fourth month of pregnancy, at this time, the fetus's eyes, ears and nose have been completely formed, and the placenta has matured, and the mother and fetus have been closely integrated. The dangerous period that is easy to cause abortion is basically over, and this month to July is the most stable period. When the fetus is sixteen weeks old, it is about eighteen centimeters long, almost as big as the mother's palm, and weighs about one hundred and twenty grams. The fetus is soaked in amniotic fluid, just like an astronaut in space, spinning back and forth lightly.
