Can it show positive when you are negative?
The question is difficult to answer because there is no information on what "it" is. Assuming that it is some sort of test result, the answer is, yes, it is possible. Most (if not all) tests are not 100% accurate and there is a small chance that the result will be a "false positive" as in the case here. Similarly, there is usually also a small probability of a false negative: that is, when the test shows negative when you are positive. Most tests are not perfect, but a trade-off between these two types of errors, with the consequences of the wrong decision being taken into account .

You have missed your period for 3 months you took a pregnancy test one said negative and one said positive you got a doctors appointment but a month away im needing input?
Pregnancy tests react with a hormone that is present only during pregnancy. If one of your tests was positive, that hormone could be present, which means you are pregnant. However, since one of your tests was negative, this could mean that the positive test was a "false positive." A "false positive" happens sometimes, but it is very rare. The only way to know for sure if you are pregnant or not is to go have an ultrasound done at the doctor's office.
