Patient's question:
What to pay attention to when pregnant in winter?Doctor's answer:
Hello:Many women engage in actions that they later regret without realizing they are pregnant. Therefore, paying attention to early pregnancy is extremely important and an indispensable knowledge for women planning to get pregnant.
I. Correct Pregnancy Testing
Generally, pregnancy test strips will indicate accuracy rates, such as 95%, 98%, etc. If no indication is provided, it does not mean the accuracy is 100%, as certain factors can cause the test strips to fail.
Failure of Pregnancy Test Strips
The failure of pregnancy test strips can manifest in two forms:
1. Pregnant but the test shows no pregnancy, meaning the test strips are not sensitive enough: Possible reasons include the test strips expiring or the reagent becoming ineffective; another reason could be issues with the reagent used by the manufacturer.
2. Not pregnant but the test shows pregnancy, meaning the test strips are too sensitive: During pregnancy, a woman's corpus luteum hormone levels rise, which can be detected in urine. Pregnancy test strips are designed to test for this hormone. However, corpus luteum hormone is present in everyone's body (including men), just in smaller amounts. Some tests are too sensitive, and even small amounts may produce a positive result, leading users to mistakenly believe they are pregnant.
Incorrect Testing Time
Testing too early or too late can both lead to incorrect results. Some people test 2–3 days after intercourse and often fail to get accurate results. Others test after being pregnant for some time, but since corpus luteum hormone levels increase with the gestational weeks, for example, after 10 weeks, the value may reach 100,000.
