Without fetal heartbeat, pregnancy test strips can usually still detect pregnancy. Once pregnancy has occurred, it can generally be detected. Regardless of whether the fetal heartbeat is present or not, pregnancy test strips can usually confirm pregnancy. However, testing with strips requires selecting the appropriate time, and pregnancy can generally be detected 30 to 45 days after intercourse. If a blood test is performed, pregnancy can usually be detected 10 days after intercourse. Between 30 and 45 days after intercourse, the fetus is growing and developing, and it may not yet have a fetal heartbeat or embryonic sprout, which is normal and does not affect the test strip's detection results, allowing pregnancy to still be detected. During pregnancy, regular blood HCG and progesterone checks are necessary. If HCG levels rise slowly and do not double as expected, beware of biochemical pregnancy, threatened abortion, and the need to determine if it is an ectopic pregnancy to avoid harm to the fetus and the pregnant woman's body. Maintaining a good mindset during pregnancy is important. If symptoms such as abdominal pain or bleeding occur, it is recommended to seek medical attention promptly to avoid delaying treatment.
