After a few days of cohabitation, pregnancy can be detected with test papers

Pregnancy can be detected by dipstick after 10 - 14 days of cohabitation. In general, it takes 6 - 7 days for the fertilized egg to implant in the endometrium before it begins to secrete human chorionic gonadotropin (HCG), and dipstick detection of pregnancy is mainly determined by detecting HCG levels in urine. After implantation, HCG levels will gradually increase, but at first the increase is small and may not be enough to be accurately detected by the dipstick. Over time, about 10 days after cohabitation, HCG levels will rise to a certain extent, at this time, the dipstick test may appear weak positive, to about 14 days, the test results will be more accurate. HCG secretion rate and level may vary from individual to individual. Some may be detected earlier, while others may take a later time. Therefore, if the test is negative after 10 days in the same room, the possibility of pregnancy cannot be completely ruled out. The quality of the test paper and the method of operation will also affect the accuracy of the test results. To strictly follow the instructions for correct operation, use qualified test paper. If there is doubt about the test results, it is recommended to seek medical advice for blood HCG test, which is relatively more accurate.
