How many days can I detect ovulation during intercourse?

Pregnancy has always been an important task for every family, so many people spend a lot of time and effort to try to get pregnant, and may even try some folk remedies that have no scientific basis. In fact, the simplest method is to have sex during the ovulation period. This is the easiest time to conceive. However, if you want to test the pregnancy result, you have to wait for a few days. So how many days of sex during the ovulation period can be tested?

As the follicle develops and matures, it gradually migrates to the surface of the ovary and protrudes outward. As the follicle approaches the surface of the ovary, the surface cells become thinner and eventually rupture. After most of the follicular fluid flows out, the egg is discharged, which is called "ovulation". If the menstrual cycle is very regular, a woman's ovulation date is generally about 14 days before the next menstrual period. Generally, the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days are called the ovulation period.

After the egg is released from the ovary, it can survive in the fallopian tube for 1 to 2 days, waiting for fertilization; the male's sperm can maintain its fertilization ability in the female's reproductive tract for 2 to 3 days, so it is easy to get pregnant through sexual intercourse a few days before and after the egg is released. Because it is easy to get pregnant through sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period. Blood hormone levels, cervical mucus, vaginal exfoliated cell examination, and B-ultrasound can all help determine ovulation.

Human chorionic gonadotropin (HCG) is a glycoprotein secreted by the trophoblast cells of the placenta. It begins to be secreted on the 6th day after fertilization. Therefore, a blood HCG test can be done 8-10 days after having sex during the ovulation period to determine whether you are pregnant. Urine HCG can be used to detect pregnancy 2-3 weeks after intercourse during ovulation. Urine HCG tests are prone to false positives, so blood HCG tests are more accurate than urine HCG tests.

For women who are planning to become pregnant, they can use basal body temperature measurement to test whether they are pregnant. Generally, a woman's body temperature is below 36.5 degrees before ovulation, and rises by 0.3-0.5 degrees after ovulation. If the egg is not fertilized, progesterone levels will drop after about a week and body temperature will return to normal. If pregnant, the body temperature remains high. The time for this early pregnancy test starts from before pregnancy until one week after ovulation. If the high temperature phenomenon still persists after one week and lasts for more than 18 days, it can be confirmed that pregnancy is confirmed.
