I was pregnant on the fifth day of ovulation.

After getting married, in order to have a baby as soon as possible, many couples will have sex more frequently in order to increase the probability of pregnancy. However, if you know the woman's ovulation period, the effect can be more effective. Is it possible to detect pregnancy on the fifth day of ovulation?

1. Can pregnancy be detected on the 5th day of ovulation?

Initially, you can check whether you are pregnant based on blood hCG 7-10 days after ovulation, but because the amount of hCG is small in the early stages of pregnancy, it is not easy to test it out. If you use a pregnancy test strip, you can check whether you are pregnant half a month after ovulation. The principle of pregnancy test is to detect human chorionic gonadotropin (hCG) in the body's urine. Generally, trophoblasts begin to secrete trace amounts of hCG on the sixth day after ovum fertilization, and blood hCG can be detected about one day later. This is the most sensitive way to detect pregnancy, and the positive hCG reaction in urine will appear later than in blood. Although many early pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period, in fact, the sensitivity of each pregnancy test strip is different, and the test varies from person to person.

1. B-ultrasound examination

The time for B-ultrasound detection of early pregnancy is usually about a week after the menstruation is delayed. You can see a doctor for a B-ultrasound examination to see if you are pregnant. If a high pregnancy score is seen under the B-ultrasound, it means you are pregnant.

The main purpose of B-ultrasound examination in early pregnancy is to confirm intrauterine pregnancy, rule out ectopic pregnancy and trophoblastic disease, estimate gestational age, and rule out pelvic masses or uterine abnormalities. Generally, a gestational sac can be seen in the uterine cavity 35 days after menstruation; at 6 weeks of pregnancy, the fetal bud and the initial primitive heart tube beating can be seen.

2. Measure blood HCG.

The early stage of pregnancy can be confirmed by testing blood HCG 10 days after intercourse. This is the earliest and most accurate testing method at present.

3. Measure body temperature during ovulation.

For women who are planning to get pregnant, they can use basal body temperature measurement to detect whether they are pregnant. Generally, a girl's body temperature is below 36.5 degrees before ovulation, and rises by 0.3-0.5 degrees after ovulation. If the egg cannot be fertilized, estrogen levels will decrease after about a week and the body's temperature will return to normal. If you are pregnant, your body temperature should be kept at a high level. The time for this type of early pregnancy test starts from the time when you are not pregnant until one week after ovulation. If the high temperature condition persists after one week and lasts for more than 18 days, pregnancy can be confirmed.
