How long does it take for implantation to occur after intercourse?

After a couple has sex, if the sperm and egg successfully combine, a fertilized egg will be formed. The fertilized egg must then successfully reach the uterus and then implant in the uterus, so that pregnancy is possible. Problems in any of these steps will lead to pregnancy failure. Everyone will have sex during the ovulation period, as the success rate of pregnancy is the highest at this time. So how long after sex will it take for implantation to occur?

How long does it take for implantation to occur after intercourse?

Generally speaking, many women who are planning to have a baby will feel a little anxious after having sex, and they want to know how many days it will take for implantation to occur. In fact, it takes some time from ovulation to successful implantation in the uterus. During this period, it is impossible to determine whether you are pregnant. Next, let’s take a look at how many days after ovulation does it take for implantation to occur? Let’s take a look together.

Generally, implantation occurs within a few days after intercourse

The fertilized egg will implant within 6-7 days after intercourse, and implantation means reaching the uterus, but because the fertilized egg is too small, it cannot be seen with B-ultrasound. It will take about 20-30 days after implantation for the small gestational sac to be visible using B-ultrasound. 3-4 days after the fertilized egg implants, a weak positive result can be detected using an early pregnancy test. The fertilized egg stays in the fallopian tube for 3 to 5 days and then implants in the endometrium. Some are earlier, some are later, and some vary greatly.

3 to 4 days after fertilization, morula is formed, and blastocyst is formed 6 to 8 days after fertilization. Implantation begins 6 to 8 days after fertilization and is completed in 11 to 12 days. After entering the female vagina, sperm can survive for 2 to 3 days. If ovulation occurs during this period, conception will occur. The lifespan of an egg is about 2 to 3 days, while it takes one day for sperm to travel from the vagina to the fallopian tube, and two days for the fertilized egg to implant. So the time it takes to conceive after sex should be 2+1=3 days.

Symptoms of fertilized egg implantation

1. The basal body temperature will drop and the lower body will bleed or cramp. Eight days after ovulation and implantation, a woman may experience a slight pink or brown stain in her private parts, and cramping may also accompany this. There may be some spotting during the menstrual period, but this is not a true menstrual period. This is the result of a fertilized egg implanting in the uterine lining.

2. The nipples are swollen and tender. After the fertilized egg implants, it will stimulate the human body to secrete progesterone. Hormonal changes can cause pain or soreness in women's breasts. If a woman's breasts feel tingling, tender, and swollen, this could be a sign of pregnancy.

3. Feeling of having a cold. Feeling tired. The large amount of progesterone (a hormone) secreted can make women feel exhausted and as if they have a cold. Almost all pregnant women suffer from this symptom and can observe other symptoms to confirm their suspicions.

4. Going to the toilet frequently. After the fertilized egg implants in the uterine wall, it begins to secrete human chorionic gonadotropin (hCG). This will stimulate the female body to urinate frequently, greatly increasing the frequency of going to the toilet.

The above is an introduction to how many days after ovulation the embryo will implant. In short, if your period has not come after 10 days, you can use an early pregnancy test to test your pregnancy yourself, or go to the hospital for a physical examination to see if you are pregnant.
