Did implantation occur on the seventh day after ovulation?

If a girl has sex during her ovulation period, she may become pregnant. After ovulation and fertilization of the egg in the same room, it will move to the uterus for embryo implantation and development. If the egg implants and develops in the uterus, it will produce hcg. At this time, the use of early pregnancy test strips can detect pregnancy. So, has the embryo implanted on the seventh day after ovulation?

1. Will the embryo implant on the seventh day of ovulation?

The man's sperm can stay in the woman's body for 72 hours waiting for pregnancy, and the woman's egg cell can survive for 24 hours after being released waiting for pregnancy. Generally, the embryo implants 6-8 days after fertilization.

2. How many days does it take to detect an early pregnancy test?

To understand how long it takes for an early pregnancy test to detect pregnancy, you must first understand how long it takes for HCG to be produced after pregnancy.

1. Waiting time for sperm and egg after intercourse: 1-3 days. After intercourse, it takes some time for sperm to merge with the egg. Sometimes he may have to wait for 72 hours, waiting for the delicate egg cell to mature and come out (ovulation period) before he can meet the fusion.

2. The time it takes for sperm and egg to combine, cross the bilateral fallopian tubes and enter the uterus: 3-4 days. After the successful fusion of sperm and egg, the sperm and egg combination will grow and move through the fallopian tubes toward the uterus, and it will take about 3-4 days to reach the uterus.

3. The time that the sperm and egg combine and linger in the uterus: 2 to 3 days. After the sperm and egg combine and enter the uterus, they have to roam inside for a while before they can find a focus and finally the embryo implants in the uterus.

4. After the embryo implants, the sperm and egg combine to connect with the embryo and the uterus. The embryo will produce HCG. HCG will appear in the urine, but the concentration is very low at the beginning. Sometimes the early pregnancy test paper will not show it, or it will always show two lines, one dark and one light. The lighter ones may be very light and almost invisible. Some people also call this shallow bar a "watermark".
