Can I use a test strip to detect pregnancy after having sex for a week?

The plan for having a baby requires active preparation for pregnancy. Generally, having sex around the ovulation period can effectively increase the chance of pregnancy. To detect early pregnancy, it is necessary to have intercourse for at least ten days. It is strongly recommended to collect venous blood and test human chorionic gonadotropin. If the test result is significantly higher than the normal standard value, the early pregnancy can be diagnosed immediately. It is a gold standard for diagnosing early pregnancy. Another simple and convenient way is to choose a pregnancy test stick or test paper and use morning urine to test, but it takes at least ten days of intercourse.

I had sex for a week and couldn't find out if I was pregnant. After intercourse, it takes 1.5-6 hours for the sperm to reach the fallopian tubes and fuse with the egg cells to form sperm-egg fusion. It takes an average of 9-13 days for the sperm-egg fusion to reach the uterine cavity. After the sperm and egg combine and reach the uterine cavity, the embryo does not implant immediately. It will find a suitable position for the embryo to implant after 2-3 days of dispersion in the uterine cavity. After the embryo implants, the trophoblast cells begin to secrete blood HCG. Therefore, it will take about ten days after intercourse before a blood test can be performed to determine whether the woman is pregnant. If the pregnancy is detected through urine test, it will take about 20 days after intercourse to detect it.

One week after intercourse, the level of human chorionic gonadotropin secreted by the uterus, ovaries and trophoblastic cells will increase. The level of human chorionic gonadotropin can be tested in the blood. If the level exceeds 10iu/l, pregnancy can be confirmed. If you have a normal menstrual period, you can use a pregnancy test strip to test your urine about a week after the due date to determine whether you are pregnant. During pregnancy, you should pay attention to rest, avoid fatigue, eat a balanced diet, and take folic acid tablets to effectively prevent neural tube defects in the fetus.

You can go to the hospital to have a blood test for HCG one week after having sex to see if you are pregnant. If the HCG test is normal, it cannot completely rule out pregnancy, because you have just become pregnant. Maybe the HCG test is normal. You can check the HCG again in a few days. If you still don't get pregnant after the check-up, it means you are not pregnant. If the examination shows that you are pregnant, you can have a B-ultrasound examination every few days to rule out ectopic pregnancy. If it is an ectopic pregnancy, it needs to be properly handled to prevent ectopic pregnancy rupture or miscarriage, which may cause intra-abdominal bleeding.
