Embryo bud 13mm is the number of weeks of pregnancy. According to color ultrasound, embryo bud 1.3cm is about eight weeks pregnant. That is, about two months pregnant. The number of days of pregnancy is counted from the first day of the last menstruation, not from the time of fertilization. It is suggested that you are pregnant now, and it is intrauterine pregnancy. Pay attention to rest, eat more fruits and vegetables, stay in different rooms, and have regular pregnancy tests.
This situation is about two months pregnant. The time of fertilization is about 45 days, but there is an error in color ultrasound examination. The pregnancy time is calculated according to the last menstruation. It is suggested that sexual life should be forbidden in the first trimester, spicy and cold food should be avoided, abdomen should be kept warm, folic acid should be taken to prevent fetal neural tube malformation, strenuous exercise should be avoided, and regular check-ups should be conducted.
After pregnancy, it is calculated according to the day when the last menstruation comes. It is impossible to infer the time of pregnancy in the same room according to the fetal size. It is only possible to get pregnant if you have sex between ovulation periods.
Generally, embryo buds can be seen by B-ultrasound in 6-7 weeks of pregnancy. The fetus is only 0.2 cm at 4 weeks, 0.4 cm at 5 weeks, 0.85 cm at 6 weeks, 7 weeks 1.33cm, 8 weeks 1.66cm and so on.
The normal growth and development of germ will lead to the slow growth of germ. Low progesterone refers to luteal dysfunction, insufficient progesterone secretion in luteal phase, or premature decline in luteal phase, which leads to poor endometrial secretion, which may lead to difficulty in implantation of pregnant eggs or early pregnancy abortion. Luteal insufficiency may be related to insufficient LH and FSH secretion by pituitary or insufficient prolactin secretion by pituitary. Some are not sensitive to gonadotropins because the pregnant eggs themselves are immature; Some of them are related to the insufficient ability of corpus luteum itself to synthesize progesterone, or to the uncoordinated ratio of estrogen and progesterone. Therefore, the low progesterone level should be treated under the guidance of a doctor and the growth of embryonic buds should be closely observed.
At the same time, during pregnancy, women's progesterone level also rises, which will lead to faster breathing and increased dyspnea. Pregnant women's demand for oxygen is increasing, which will also prompt pregnant women to breathe faster.
At 10 week of pregnancy, the crescent-shaped placenta was seen by B-ultrasound, and the gestational sac began to disappear. By the time of pregnancy 1 1 week, the gestational sac disappeared completely and the placenta was clearly visible. It is worth noting that the size of the gestational sac changes every gestational week, and the development of each fetus is fast and slow. As long as the size of gestational sac and embryo change is within the normal range and the fetus develops normally, there is no need to worry too much.
