Picture of pregnancy test paper after 9 days of intercourse

If your menstruation is regular and you use an ovulation test strip 9 days after having sex, the chance of pregnancy is basically zero. The normal menstrual cycle of a woman is about one month, and it is easy to get pregnant if you have sex during the ovulation period. The ovulation period is between two menstrual periods. Nine days after intercourse, the sperm and egg have just combined into a sperm-egg combination and are still retained in the ampulla of the fallopian tube and have not yet been transported to the uterine cavity. Therefore, no villus tissue is developed, and of course it is not easy to release human chorionic gonadotropin, which is the HCG level tested by early pregnancy test paper. Even if you successfully get pregnant this month, 9 days of intercourse is not long enough for a positive result to appear on the test paper. It is recommended to conduct an early pregnancy test after the menstruation has stopped for more than 35 days. If the menstruation has stopped for less than 35 days and it is urgent to confirm whether you are pregnant, you can take a blood test to check the HCG level to confirm the diagnosis.

Whether pregnancy can be detected 9 days after intercourse depends on what the test items are, so that in-depth analysis can be carried out. For example, if you want to use urine HCG to determine whether you are pregnant 9 days after intercourse, the time is too early. It takes about 11 days for the sperm and egg to combine and reach the pregnant mother's blood circulation system and then reach the urine. 9 days is too short and there will be deviations, so pregnancy cannot be detected.

For example, if you want to diagnose pregnancy based on the human chorionic gonadotropin blood test, it is possible now. You can do the blood test 8 days after intercourse, and the accuracy can reach 99%. After the result comes out, if it is significantly lower than the normal range, it means you are not pregnant. If it is higher than the normal range, it means you are pregnant. You can do B-ultrasound at about 42 days to determine whether it is an intrauterine pregnancy or an ectopic pregnancy.

If the patient can determine the ovulation period on the day of intercourse, whether she is pregnant can be determined by testing blood and urine HCG 9 days after intercourse. If the patient cannot determine the ovulation period on the day of intercourse, the patient may ovulate and become pregnant within 3 days after intercourse. Therefore, in order to more accurately determine whether pregnancy is present, it is recommended that the patient check blood HCG about 10 days after intercourse and urine HCG about 13 days after intercourse to determine whether pregnancy is present.
