Pregnancy is a complex and lengthy process, where the egg and sperm meet to complete fertilization and union, and then enter the uterus. And the embryo develops and matures in the uterus, and there are different developmental changes at each gestational week. So, how long does pregnancy take to enter the uterus?
After the fertilization of eggs and sperm is completed, women can conceive and it usually takes about nine days to enter the uterus. Generally speaking, after the egg and sperm combine in the fallopian tubes, it takes four to five days to reach the uterus, and then three to four days to implant in the uterus. Therefore, this process takes at least nine days, and only when the embryo truly enters the uterine cavity can it be considered pregnant.
The initial appearance of pregnancy is the gestational sac, at which point the fetus has not yet fully formed, but a fetal bud has already appeared. The gestational sac is initially very small, it is a transformation process from small to large. Usually, in the early stages of pregnancy, the gestational sac can be seen through ultrasound examination. However, due to individual circumstances, some pregnant women may be affected by the duration of conception, which can affect the time to see the gestational sac.
After reaching the uterus, the gestational sac will no longer move freely, but it will gradually grow. Pregnant women can use various examination methods during pregnancy to check the movements of the fetus. After pregnancy, it is important to take good care of the fetus and avoid vigorous exercise as much as possible. In the early stage, it is necessary to timely supplement progesterone hormone, develop good dietary habits and sleep schedule to promote good fetal development.
