How long after sex can you detect pregnancy?

We all know that if a woman's menstruation stops or she experiences nausea and retching after normal sexual life, she may be pregnant. So, how long does it take to detect pregnancy after sexual intercourse? How long does it take before you can use a pregnancy test stick or pregnancy test paper to test? Let’s analyze it together below.

How long does it take to detect pregnancy after sexual intercourse?

At least ten days after having sex, you can use an early pregnancy test. If you are not sure whether you are pregnant, you can wait until after your menstrual period to go to the hospital for a detailed B-ultrasound examination.

The sperm and egg combine and stay in the bilateral fallopian tubes for 3-5 days before the embryo implants in the uterine wall. Some are earlier, some are later, and some are very different. Morulas are produced 3-4 days after fertilization, and embryos are produced 6-8 days after fertilization. Embryo implantation begins 6-8 days after fertilization and is complete on 11-12 days. After entering the woman's vagina, male sperm can survive for 2 to 3 days. If it encounters ovulation during this period, pregnancy will occur. The lifespan of an egg cell is about 2-3 days, while it takes one day for male sperm to travel from the vagina to both fallopian tubes, and two days for the embryo to implant. Therefore, the time for pregnancy should be 2 1=3 days.

Under normal circumstances, if you have sex after ovulation, the chances of getting pregnant are very high. When the sperm and egg combine to form ovulation, it is necessary to comprehensively consider various factors and choose the most ideal pregnancy day, which is generally arranged around 14 days before the woman's menarche. The miscarriage rate is higher if intercourse is performed after 17 days. Because after the egg cell is released, it usually only survives 12 to 24 hours, and the sperm in the female reproductive system usually only survives 1 to 3 days. Therefore, generally speaking, it is easiest to get pregnant from 3 days before ovulation to 1 day after ovulation. It is not easy to get pregnant if you have sex too early or too late.

Pregnancy can be detected a few days after the purpose of daily life. Based on the research of human body clock, biologists show that the physiological phenomena and functional states of the body change continuously within 24 hours a day. From 7 am to 12 am, the human body function state shows a continuous upward trend. The end of 13:00 to 14:00 is the time when the body function is at its lowest during the day; it rises again at 5:00 p.m., and drops sharply after 11:00 p.m. It is generally believed that 9-10 p.m. is the best time to have sex and get pregnant. In addition, women lying down for a long time to sleep after sex is beneficial to the movement of sperm and increases the chance of sperm-egg contact.

How many days after sexual intercourse can pregnancy be detected? It takes some time to test whether pregnancy is achieved after sexual intercourse. The egg begins to secrete HCG on the 6th day after fertilization. A blood HCG test 9-11 days after intercourse can diagnose whether you are pregnant. If you use an early pregnancy test strip, you can detect it two weeks after sexual intercourse. Morning urine should be used for the test, which is more accurate, so you can know whether you are pregnant at the earliest time.

Can you get pregnant during the safe menstrual period?

Many men and women like to have sexual intercourse during the safe menstruation period, thinking that in the safe menstruation period they can not only enjoy sexual life comfortably, but also get rid of the worry of getting pregnant. In fact, this idea is wrong, because you can get pregnant during the safe menstruation period. Generally speaking, the chance of getting pregnant during the safe menstruation period is small, but this does not mean that you will not get pregnant if you have sex during the safe menstruation period, because in many cases women will ovulate earlier or later, and the judgment of the safe menstruation period will become invalid. Identifying the safe menstrual period only reduces the chance of pregnancy. It does not guarantee that you will not get pregnant.

Even though the rhythm method of contraception has a certain effect, if you do not want to get pregnant, it is best to take more insurance measures to prevent pregnancy. In fact, modern women are under great work pressure, so in many cases their menstrual period and ovulation period are not very normal, so we can't trust the safe period of menstruation too much, because this may be a "forbidden zone". After all, the safe period of menstruation can only reduce the chance of pregnancy, but it can not reduce the chance of pregnancy to zero.
