How many days of pregnancy can you use test strips to detect
After becoming pregnant, women usually use pregnancy tests to confirm their pregnancy status. So, when can I take a pregnancy test? From experience, test strips can generally be used for testing after the menstrual period has been delayed for seven days. Because the normal menstrual cycle is about 28 days, if the cycles are consistent, you can test whether you are pregnant one week after the pregnancy period. But be reminded that even if you are pregnant, the HCG hormone in some women may not be high enough, and it may not be detected during this period. Therefore, it is also important to use test strips correctly for testing.

Test strip pregnancy test is actually a very accurate detection method, with an accuracy rate of about 95%.

At the same time, the storage and expiration time of the test strips are also factors that affect the accuracy. Using expired or poor quality test strips will obviously reduce its accuracy. Therefore, before using test strips, pay attention to the purchase date and shelf life to avoid using expired test strips.

Two results will appear: one is if two bars appear normally, then you are pregnant; the other is if only one bar appears, then you are not pregnant. Pregnant. It should be noted that the results are analyzed in a concentrated manner and do not over-judge the single-bar detection errors.
