I got pregnant again after having sex for 11 days and the blood test showed no pregnancy

Only by passing on the family line can our human race be carried on. Therefore, from ancient times to the present, we humans have attached great importance to pregnancy and childbirth. In ancient times, there were even special sacrifices to protect their own people for a prosperous career. Pregnancy is also a high-risk thing. We have to be cautious during the pregnancy process. Therefore, many people start using early pregnancy test strips to measure whether they are pregnant in the early stages of pregnancy, so that they can better protect their bodies in the early stages of pregnancy. So how come I got pregnant again 11 days after having sex and the blood test showed no pregnancy?

Blood test can be said to be a more accurate method of pregnancy test. Generally, it can detect whether the woman is pregnant 10-14 days after intercourse. The reason why the blood test shows no pregnancy after 11 days of intercourse but the woman becomes pregnant again during this period may be due to individual differences and the pregnancy time is relatively late.

Sperm can survive in the body for 72 hours. Within this 72 hours, pregnancy is possible at any time of ovulation. It takes about a week for sperm and egg to combine to form sperm-egg fusion and complete embryo implantation. After the embryo implants, it begins to secrete chorionic gonadotropin, which takes about three days, or about ten days after ovulation, for blood chorionic gonadotropin to detect pregnancy.

To determine whether a woman is pregnant, a blood test is more accurate. However, due to the uncertainty of the fertilization time, a woman may become pregnant again after 11 days of intercourse and a blood test shows no pregnancy. In addition to blood tests, early pregnancy can be checked using early pregnancy test strips. When using the early pregnancy test paper, you should use the first urine in the morning. The hcg value in the urine is the highest and it is easier to test. Early pregnancy test strips are less accurate than blood tests in detecting early pregnancy, but they are convenient and easy to use.

Most women will experience early pregnancy reactions such as chills, dizziness, fatigue, constant sleepiness, drooling, poor appetite, preference for sour food or aversion to greasy food, nausea, and vomiting in the morning about 6 weeks after menstruation. This is also a way for one to identify pregnancy by oneself. During pregnancy, you must pay attention to rest, pay attention to diet, do not stay up late, do not smoke or drink, and the diet should be light and nutritious.
