Under normal circumstances, the ovulation period is in the same room, with high -quality eggs excreted, and after encountering high -quality sperm, sperm and eggs are combined to form a single -cell fertilized egg. After forming fertilized eggs, the fertilized eggs enter a level -by -division state.Fertilized eggs need to enter the uterine cavity along the fallopian tube.The combination of eggs and sperm is very fast, and sometimes it will be completed in a few hours.However, fertilized eggs take a long time.
After the combination of sperm and egg cells, it will stay in women’s fallopian tubes for about 4 to 5 days.After that, the fertilized eggs will move to the direction of the uterine cavity under the action of fallopian tube peristalsis and cilia. After entering the uterine cavity, it will take about 2-3 days to bed.By bed is the fertilized eggs sticking to the endometrium.This process generally requires about 6-7 days.That is to say, fertilized eggs generally need 6-7 days to move to the uterus, and then find suitable places to plant it, and camps to cultivate embryos.If the fertilized eggs, such as fallopian tube obstruction, adhesion, inflammation, etc., are caused by various reasons, which cause damage to fallopian tube function and cannot transport fertilized eggs normally.
When we are in bed, some sensitive women will feel the phenomenon of lower abdomen pain, acupuncture or sourness, a little vaginal bleeding, etc. This is a phenomenon that may occur in the bed.
After the fertilized eggs are in bed, the synthetic layer of cells begin to secrete the choric membrane to promote gonadotropin, that is, HCG hormone.It is mainly reflected in blood and urine.If the blood HCG examination at this time is performed, you will find that the value of HCG will increase significantly. You can detect whether you are pregnant. It is the earliest detection method to know whether you are pregnant.If menstruation does not come for more than 2-3 days, you can also check whether you are pregnant with early pregnancy test strips.About 20-30 days after bed, about 35-40 days of menopause, you can see the gestational sac in a color Doppler ultrasound.
Generally speaking, after 10 days of the same room, go to the hospital for blood testing for HCG, and you can know whether you are pregnant earlier.
