What symptom does ectopic pregnancy have 3 months

First: in the first month of pregnancy (1-4 weeks), if the menstrual cycle of a pregnant woman is once every 28-30 days, the time of pregnancy is calculated from the first day of the first menstruation, and the second week of pregnancy is the time of sperm egg combination and conception. After fertilization, the cells continue to divide and quickly become a solid cell mass, which is called sangkan embryo. 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. At the third week of pregnancy, the outer membrane of the cell mass is removed to prepare for implantation. At this time, there are about 150 cells and they differentiate into two parts: the inner cell group is the later fetus, and the outer cells will form placenta and amniotic sac in the future. When the blastocyst is implanted into the spongy endometrium, which is rich in nutrients and oxygen, and the implantation is completed, a large amount of oxygen, protein, vitamins and other substances in the blood of pregnant women enter the blood stream of the embryo continuously through the thin villous wall. At the fourth week of pregnancy, the blastocyst has been firmly planted in the human uterus, where it grows and develops into a very small embryo. At this time, to the time of menstruation, the initial feeling of pregnant women is breast fullness and tenderness, at the same time, menstruation and future tide, should consider whether pregnant. Gestation 3-4 weeks, known as fetal bud period, fetal bud about 0.5-1 cm long, like a small hippocampus, this period is an important organ growth period.

Second: if the second month of pregnancy (5-8 weeks) to the fifth week, menstruation is still the future tide, the basic temperature is high temperature, lasting more than 16 days, can go to the hospital urine test, if the pregnancy test is positive, can be basically determined as pregnancy. At this time, pregnant women begin to have pregnancy reactions, such as loss of appetite, anorexia, nausea, vomiting, drowsiness, fatigue and fear of cold, and even sentimental and irritable mood. Some parts of pregnant women's body also began to change: breast swelling, nipple areola black, urine and urine and leucorrhea increased, these phenomena are physiological phenomena, do not have to feel anxious. In the second month of pregnancy, the embryo has a body and a tail. It can distinguish between the eyes and the small ridges on the hands and feet, which are the future fingers and toes. At the fifth week of gestation, the neural tube gradually formed. These neural tubes will develop into the brain and spine in the future. About 7 weeks of gestation: the fetus is about 2-3cm long and weighs about 4G. It has grown hands and feet, and can be seen from eyes, ears and mouth. Its face looks like a human.

Third: in the third month of pregnancy (9-12 weeks), when the pregnancy enters the ninth week, the face of the embryo has obvious features, the body of the embryo is elongated, straightened, and the tail is shortened to disappear. By the tenth week, the embryonic period is over and the fetus is in its infancy. The human features of the fetus are obvious, with fingers and toes visible. The umbilical cord is gradually lengthened, and the fetus can rotate freely in the amniotic fluid. At this time, the fetal heart, liver, stomach, intestines, etc. are more developed, the kidney is also gradually developed, producing urine, and with the ureter, the fetus can carry out micro excretion. By the end of 11 weeks, the womb of pregnant women is as big as a fist. If you press around the womb, you will feel pressure in the lower abdomen or heel cramps, and the frequency of urination will increase. At this time, the pregnancy reaction gradually alleviates and will soon disappear. Pregnant women at this time will feel more swollen breasts, areola, nipples began to have pigmentation, black color.
