What symptom does fertilized egg implantation have?
summary
Usually, the blastocyst begins to implant on the 6th to 7th day after fertilization. Implantation is already in the uterus, but it is still small at that time. It can not be seen by B-ultrasound. It is only 20-30 days after implantation that the small gestational sac can be seen by B-ultrasound. However, 3-4 days after implantation, that is, after the 10th day after ovulation, the weak positive can be detected by early pregnancy test paper, but some may not be detected. If this is the case, then what are the symptoms of fertilized egg implantation? Let's talk about it now.
What symptom does fertilized egg implantation have?
Generally, after ovulation, if the sperm and egg normally combine, they will be implanted within 7 days. The fertilizing ability of ovum is about 12-24 hours, but the fertilizing ability of sperm and ovum is only 1-2 days. The egg is fertilized in the ampulla of the fallopian tube, then the fertilized egg moves slowly in the fallopian tube and enters the uterine cavity after 3-4 days.
Generally, the posterior wall of the uterus is slightly more than the anterior wall, and the midline is more than the lateral wall. The whole process of the movement of the fertilized egg in the direction of the oviduct to the uterus after the union is quietly carried out, and the mother does not feel anything.
After fertilization, it takes 4-5 days for the egg to go from the fallopian tube to the uterus, and it takes 3-4 days for the egg to stay in the uterine cavity. This process takes a total of 7-9 days. Therefore, if you use a more sensitive (15 international units) early pregnancy diagnostic box, it will take about 10 days after ovulation; It is very normal and reasonable to detect hCG with normal early pregnancy test paper (25 IU) about 15 days after ovulation.
matters needing attention
The above feelings vary from person to person, not that everyone is like this, but after successful implantation, they generally feel tired and their appetite drops. Therefore, if they haven't come after 10 days of menstruation, they can use early pregnancy paper to test whether they are pregnant.
